Dutch startup Nimbuzz , which bills itself as the “mobile Skype” today releases an IM application for Android phones which ties together multiple messaging tools (Skype, MSM, Yahoo, ICQ, Google Talk, etc.) via a single interface. The Nimbuzz trump card is Skype VOIP. Unfortunately the Android app doesn’t yet include this but it is available in the iPhone app. The Android application also supports many local social networks like Hyves (dominant in the Netherlands) and a nifty time-sensitive user interface which does things like detecting how long a user presses on a contact; a quick click opens the contact’s profile while a long click opens a chat window. Nimbuzz has also released to us the results of a survey of 21,000 users which reveals some interesting differences in how people in different parts of the world communicate.
