If you are personally holding many IM / Social network account and frustrate signing in one by one everyday, here are 2 tools recommended to you as below:
I personally choose Nimbuzz because it support Skype account and most importantly it compatible with my mobile phone, so that, I’m able to treat my phone as Skype phone too 🙂
The bad things for these 2 IM tools are:
1. They mostly text and minor emoticon.
2. They have no Winks like what’s in Live Messenger, shower smiley face in AIM.
