This week in social media, Facebook approved a dogecoin tipping app, social media prenups are a thing now, Instagram updated its app with new tools, Pinterest and Twitter keep upping the advertising, and CIA joined Twitter and Facebook for some reason. It's time for Social Media Saturday!

Instagram: App Update Gives More Filters and Photo Editing Options

Instagram launched an update for the iTunes store and Google Play called Instagram 6.0. The new tools allow you to change how much filter strength you want to apply, as well as adding detailed abilities to adjust brightness, color, saturation, and more.

While adding lots of in-depth features, the photo-centric social media network managed to find a way to make certain levels of filter customization simple. "When you go to select a filter, you'll now see a new wrench icon," states Instagram's blog. "Tap it and you'll find a tray of photo editing tools ready for you to explore. You can also now adjust how much of a filter you apply to a photo by double tapping the filter icon." Go here for more details on the new apps.

Facebook: So Dogecoin Tips, But Wow! - Very Traffic Drop

This week, Facebook approved a cryptocurrency tipping app -- the first of its kind -- but it's not for Bitcoin, as you might expect. It's the Dogecoin Tipping App, a way to spread the lovable digital currency based on the love/hate-able Doge meme.

Facebook also approved a Multicoin Tipping App that includes several other cryptocurrencies, including Dogecoin, so the official Dogecoin Reddit page excitedly called the approval by Facebook a "double hit!"

Speaking of profitability on Facebook, some online content makers have been noticing a drop in traffic from Facebook over the past few months, after Facebook changed its algorithms late 2013 to make News Feeds more tailored to each user.

This week, the social media giant explained why that change is negatively affecting companies trying to reach users.

On a blog post for business news Facebook's Brian Boland explained why organic reach for businesses on Facebook is declining. It basically comes down to this: News Feed was updated to show users exactly and only what is relevant to their interests. But as Facebook has ballooned in popularity, the average user could have up to 1,500 posts that could be shown to them, based on their likes, friends likes, and their profile interests (some users, Boland noted, could be shown as many as 15,000).

Obviously, no user is going to need or want 1,500 posts to look at every time they log in, so Facebook whittles that down to about 300 posts to avoid overload. While Facebook has tried to clean up News Feed spam and show high-quality posts, simple numbers mean that some legitimate posts are going to end up on the cutting room floor.

Twitter: More Native Ads with Namo Media Acquisition

Twitter has been under a lot of pressure to generate accelerated profits after its IPO late last year, which necessarily means more ads.

In an effort to ramp up its advertising, Twitter said on Thursday that it had acquired a native ad specialist company, Namo Media. "In our conversations with the Namo Media team, it became clear we share a vision for how native advertising can improve the state of mobile app monetization for marketers, app publishers, and users," said Twitter's VP Kevin Weil in a blog post.

The terms of the deal were not disclosed, but the Wall Street Journal reported it was less than $100 million. Namo Media joins mobile ad company MoPub, which Twitter acquired last October, in its first round push towards ramping up advertising and profits.

Pinterest: Self-Service Ads for Small Businesses

Facebook will always be on the hunt for ways to better serve small businesses, despite its (ironically) detrimental popularity that depopulates less well-known publishers from users News Feeds, but Pinterest just announced a bid that could steal some of Facebook's small business-revenue thunder.

A new ad system in Pinterest will allow small businesses to advertise "promoted pins" and pay per click -- rather than the cost structure generally used for big advertisers, which are based on cost per thousand viewers. According to the Wall Street Journal, this takes a page straight out of Facebook's 2008 launch of self-service ads, and is led by Don Faul, Pinterest's head of operations, who was behind Facebook's similar 2008 launch. Pinterest's recent changes in user interface and ad policies are part of an effort to shore up a justification for the $5 billion valuation it recently received in its last fundraising round.

Other Social Media News: The Miscellaneous and Weird

Sometimes the social media developments of the week don't fit a certain category.

For example, this week, Microsoft added Twitter (and several other entertainment apps) to its Xbox One console in a way that syncs the topic with whatever TV show you're watching through the Xbox One.

It provides a live feed with at the bottom of the screen, which looks and sounds distracting, but perhaps less distracting than constantly checking your "second screen" for the Twitterverse's reaction to every development. Check out the Xbox blog for other additions to the console.

From the miscellaneous to the weird: This week, the Central Intelligence Agency joined Facebook and Twitter, in what is obviously an attempt at image-softening PR.

Cute right? Or manipulative, depending on your viewpoint.

The official explanation for the shift towards social media was given in a CIA press release (via ABC News). "By expanding to these platforms, CIA will be able to more directly engage with the public and provide information on CIA's mission, history, and other developments," stated CIA Director John Brennan. "We have important insights to share, and we want to make sure that unclassified information about the Agency is more accessible to the American public that we serve, consistent with our national security mission."

Which begs the question: does Twitter count redacted characters against the 140 limit?

In one final weird social media development this week, apparently more couples are getting so-called "social media prenups."

Yes, that's officially a thing now, according to the investigative journalism of Good Morning America, which reported that the 21st century prenups address what information is acceptable for each side of the relationship to share about each other, and what consequences follow a breach of said contract. According Ann-Margaret Carrozza, a New York-based attorney who draws these things up for couples, a penalty posting embarrassing information or media for someone who makes below $5 million typically runs to $50,000 per post online.

Yikes! Still, prenups for the digital age like that might be more effective in stopping the sickening phenomenon of "revenge porn" than the current state-by-state piecemeal legislative approach. But if nothing else, it'll make husbands and wives think twice about venting after an argument with one of those TMI posts.
