(I'm going to assume you're asking for the ability to create profile posts (alongside the ability for others to comment on them and / or "like" them) + being able to "follow" users + a sort of personal activity page that lists out what members you follow did recently (their regular posts, topics, profile posts, merit, etc.) to be implemented)

The chance of theymos (the head admin of Bitcointalk) implementing these features into the current software package this forum runs on is effectively zero. There is, however, a new forum software project in development, with plans to replace Bitcointalk's current highly modified version of SMF 1.x with it once it's reached a stable version. Feel free to visit the "New forum software" board and suggest those features there. Even then, the functionality in question doesn't really mesh well with the old school forum vision of Bitcointalk. But hey, you're free to try.

P.S. If you're asking for this forum to be turned into a Facebook-like social network, uhh... no. This is a discussion forum, not a traditional social network. If you're looking for that experience, there's Facebook itself as well as hundreds of both blockchain-focused and regular traditional social networks on the market. I'd suggest you check them out if that's the experience you're looking for.
