According to (of all places) Wikipedia, Yahoo is planning an update to the Mac version of its messenger. It seems that the timing might be right. When Yahoo and MS integrate their messaging protocols, it will mean that competition will be driven, not by the size of their respective networks (the size of the user base) but by the quality of the IM app. Right now, Yahoo messenger is old, ugly, and feature dead. Its about time for an update, and now is the right time. Does anyone have any concrete information on this?
