@jenna awesome indeed, love it!
I use it to coordinate games on the xbox with friends who aren’t on xbox at the time, or to kill time at work on my breaks. And as a private chat client. wooo. I also follow people in my industry in the area I’m going to move to so I’m up to date with what’s going on up there.
I think there are a lot of people who use it to flex their exhibitionism muscles and to gain a sense of importance in the mundane (guilty), but I think many users also take advantage of it as a medium to connect. I originally signed up because some of the communities I visit have used it in the past to connect at expos, conventions, concerts, festivals, and other large-venue areas where large groups of people can coordinate with one another via mass txts.
