After serious consideration, I'm probably going to move to multiply, myself. My id was created a couple days ago (same ID as here), but I think I'll actually move journals over to it.
Most people that aren't on ask "what's so sexy about it"? The answer is it does everything we do here, plus a lot more (pictures, music, etc... but not terrible like myspace). The things its missing? The front page.
Now most people feel like there will be no more growth in the /. circle, which I feel is incorrect. The growth will be probably the same, but the reason will be different.
Right now, growth comes from a new slashdot id that stumbles onto us. We have lots in common, cause, most likely, the new person is a geek like the rest of us.
In Multiply, the new friends will come from other friends friends (follow that?). Basically, I'll become a friend of one of blinder's friends. Since blinder and I have a lot in common, his friend will, most likely, be compatable with me, also, so then the circle grows. Its just as open ended as the growth we have here, even more so, especially in the beginning.
I'd suggest everyone getting an ID, and start friending everyone up. I'd also suggest setting up your messages to only get the 'daily' email, not new emails for every little thing (as that is annoying as hell). Maybe do a weekly thing, who knows. Anyway, I'll still be around here, but probably not many more journals (especially since my journals have fallen off)...
Oh, and its easy to keep in touch with those that DON'T move there, as you can setup an RFF feed for your friends' journals here...
