Well, it's popular because it keeps people in contact! You can see what everyone is up to, write messages directly to people all around the world. They have some pretty cool applications, like maps where you've been, write notes for everyone to see. It's basically it's a blackberry but for people who don't have blackberries, and who want to keep in touch. It's a really cool way for me, at least, to keep in touch with myfriends while I'm out of the country for the last few years.
Yeah, I check their website to download the app like every week, and I just quickly check the install version before installing and it's always 1.0.18.
