Hashable allows you to keep track of all your social connections (as if there aren’t enough websites allowing you to do that) and also allows you to find new people to connect with. You can share this information over Twitter, you can choose to keep it all on Hashable, share it on both networks, or just keep everything private.
There’s a point system involved with the site; you earn points for connecting with people and for site activity. I don’t particularly care for point systems, but some may find it useful or interesting.
As with Twitter, you can also make up your own hashtags on Hashable, or you can stick to the site’s most common ones: #intro, #justmet, #invite, #lunch (for documenting the time and reason you met with someone), #meeting, and many more.
I thought the concept was pretty interesting, but I don’t think I’m going to be using the site. Someone else may find it useful, though – hence this blog. However, the website is in beta, so hopefully more features will be added over time and it’ll become more useful. Try it out and let me know what you think! 🙂
