Anyway, it seems like 5-10 years too late. I remember when I was in school (till 2003) that ICQ was huge. People knew their ICQ numbers by heart, and it was as important as e.g. WhatsApp or Facebook is today. It even anticipated microblogging - you could set a custom "status message", and people would check each others messages to see what others were doing. They had a lot of features that were not to different from what Facebook has today - you had Flash based minigames, a personal homepage-like area etc.. And of course they had a huge network advantage. I really wonder how they dropped the ball...
