Which one is the best? I used all of them and I think Kakao is the best although I uninstalled it because of privacy reasons. They said in their website that they follow South Korean laws and theirs servers are in South Korea. I am just not comfortable with that. Liveprofile has great potential but its too buggy. I like its interface and facebook integration, but half the time it won't work. Beluga's poor interface makes me mad every time I open it, so going to uninstall it. GroupMe has some kool features but it doesn't have video support. KiK is the fastest but it won't even let you send a pic. I still love KIK and waiting for a pic/video support update. Not too sure about WhatsApp yet. Just downloaded. Looks ok so far. So, guys, whats your favorite instant messenger?
