[mynegation]

I am not criticizing it, but I am not using it either (I did use it, out of novelty and because of couple of friends of east Asian descent).

Ultimately, it is not about features or quality, but what the majority of your social network uses. Personally, I would dispense with all the messengers altogether. I usually ask people to e-mail me for the non-urgent stuff, call me for really urgent stuff, and for everything in between there is text and iMessage.
