Twitter is using Facebook to get ahead in digital growth.

Twitter has been going through many different and rumored upgrades over the past two weeks: first it was updating their login page, which some complain looks like Facebook; and this week Twitter has introduced photo-tagging, similar to Facebook. These two social media platform companies are becoming similar animals.

There is more to Twitter's photo-tagging system than some people think. But not everyone agrees with Twitter's new development.

The company's new photo-tagging system is its way of catching up to the ever changing digital media landscape. Twitter's investors however, think they are too slow in both earnings, and technological growth.

According to Re/Code, Twitter's new feature lets you identify any person in pictures that you have posted to the service. Previously, you have had to use Twitter's @-reply buttons to mention other people.

Twitter can sometimes appear to be like a foreign place that is more geared towards networking, self-promoting and sharing news, as opposed to a Facebook-like platform for social interaction. But, Twitter seems to be incorporating more of the social aspect into its design lately with its new profile and website styling. All of these new features borrow heavily from Facebook, the Tech Times reported.

This is how the Twitter photo-tagging works. The company recently sent an update to its iOS, and Android apps this week. There are two things to know: firstly, you can tag up to 10 users in photos and it does not count towards your 140 characters. All you have to do is hit the "Who's in this photo?" button, and then add people to the list.

Secondly, you can attach multiple photos to a single tweet, up to four photos. Just follow the usual process in the app, and tap the ones you want. They will appear embedded along with the tweet, NBC News reported.

Twitter has seen at least one billion people sign up to the service over the past eight years of its existence, but they can only claim 241 million people regularly returning to tweet. That means, approximately, for every 10 people who may try out this new Twitter thing, only about 2.5 of them on average keep coming back.

Twitter still seems to be more geared towards professional and business use, than towards small social interactions. Facebook is coming at it from the opposite direction, trying to get more professional and less purely social.
