Facebook Acqhires Storylane Because It’s Time To Fight Tumblr
techcrunch.comYou know, I'm pretty sure that Tumblr wouldn't have nearly the appeal it does if users had to post everything under their real name...
This is an overly simplistic statement. They're completely different tools:
Tumblr is a tool for developing (micro?)blogs about any topic under the sun -- therefore identity isn't really relevant (unless you WANT to be an authoritative source on a topic, for which a real identity WILL take you further than a pseudonym on average)
Facebook is about connecting people -- REAL people; therefore pseudonyms take away from that experience. If pseudonyms were in any way positively correlated with the experience, Myspace would still be going strong.
Facebook already proved that a social network where real identity was encouraged could succeed. So saying that Tumblr wouldn't be as popular if it made users use real names would be misleading. I don't think the popularity of Tumblr was because they allowed users to not use their real identities.
I suppose this will be a happy thing for some people but I wouldn't touch it with a ten foot pole. In my opinion, Facebook is too shady.
