Imhaha is a new online instant messaging service website, quite similar to meebo. It offers popular services like MSN, Yahoo, AIM, ICQ, and also QQ, which has the most users in our country (though I don't use it much). I wonder if they are targeting the huge Chinese market, but unfortunately, it does not support gtalk, which I use often. I logged in with my MSN, and the interface inside resembles Apple's design, and it looks pretty nice.
