In short- No! I came across this comment on mark cuban’s ”Some predictions come true, some don’t“ post today-

1. You may have been too lazy to do anything about “communities of interest” at the time – but it certainly isn’t too late. I don’t think huge social networking sites are the end all answer – I think the most popular “social networking” sites will be relatively small, focused and be used fanatically.

Time will tell whether this is true, but I think it will be. Myspace won’t be the most thriving social network in a couple years in my opinion. It’s only a matter of time before niche sites really become popular…or blogging just takes over by combining the best of social networking and blogging into one!
