I guess it's best to come from the horse's mouth...yes we are growing... we're still in private beta so that makes a huge difference. plus ST! and FF have two very different purposes. we try to make it easy to get to all of your friends' activities (regardless if they're on ST! or not) and FF is a place to have conversations...make sense? - Matt Galligan

Wow, Matt, badass! I appreciate your response and yes that makes sense. ST!'s design/UI is excellent for reading activity streams (and the FB integration hugely enhances it). I've been wondering what your product will look like when it's ready for public release...with all the FF and Twitter buzz, it seems ST! could get it on the action. I'll follow you here and see how things develop. - Bryan Landers
