Fun on the Web Oct. 22, '10 Is This the New Social Network

For those of us who blog here, it may be sacrilege to say
http://www.tumblr.com/ is the new social network, but ease of use, photosets, no ads in your theme, private posts, bookmarklets,and 3rd party apps may make make this the replacement for Facebook or dare I say it Blogger? Hundreds of gorgeous themes to choose from or make your own, copyright your work, use custom domains, tweet, or import your work from elsewhere. I know I have to check it out.
