42blips.com seems to be a social networking site for Spec-Fic geeks. It is a delicious.com/slashdot/digg type of link site, but narrowed down to spec-fic.
The main page shows latest hot stories and you vote on them. All of the stories are tv/film Sci-Fi and not literary SF.
(Note to J. Erwine – you should join and use this to announce new SamsDot releases; you might get a few new readers.)
I have put it in my “good morning” list until I figure out if it useful to me. I read none of the popular stories because I don’t care what is going on in the private lives of SciFi TV actors.
