I'm hosting a poll on dribbble.com/shots... but you can answer here too. I like the idea of Steptalks as a play on small talks and describes the idea behind the social network very well too.
I still prefer Subcafe, the "cafe" part fits well with chilling around on the site :)
But Steptalks sounds nice, better than Subtalks for that matter, I think...
I made the switch. I guess step talks and money walks.
