For those of you who grew up on Forums, you know that it’s so, so much more.

I'm still sold on the responsibility aspect of using all this data. I agree it'd be a little creepy to connect out of the blue based on some data that I know is out there but didn't know YOU knew it is out there.
I think if you take care of that piece of data - mainly by not leading with it in conversation - it can be used.
Just be responsible.
Also, I totally miss IRC, forums, etc.
