IMO.IM - better than Fring and Nimbuzz

I've tried Fring and Nimbuzz on Android, only getting worse. Logon to Skype takes ages. I thought it was Skype problem. Today, after trying out IMO.IM, I know it's not Skype's fault. IMO.IM logs on Skype fast. Perhaps light weight really is the killer feature of all apps nowadayds.
