Yes, I can. The networks work fine. If people need more than "this works fine, it's free, and you can use it instead of the other way around" as a reason, the people are broken.

20 years ago we hardly had cell phones and that was just fine, if you actually loved your Grandmother you'd always find a way to send her some baby photos... and now we start to cry because Diaspora is kinda basic? Even though that would change real quick if only 5% of the FB users would switch to it. I think that's silly, so I for one am reachable by phone and email, and my friends are always welcome to join me "on the actual web". Until then, I'm not supporting them in their self-harm: for whatever reasons people use Facebook, I try to avoid being one of them (edit: one of the reasons, that is).
