Eh, I personally see no problem with it.

I find fb a great way to keep up with the friends I want to keep up with, to plan get-togethers and such.

There is an effective ignore feature on fb, so if someone is expending too much bandwidth (imho) yammering about what they had for dinner or whatever, I put them on ignore. Easy-peasy.

Nowadays, I personally find fb much more useful and relevant to me than TE, which I feel (again, imho) has, over time, become full of irrelevant chatter. I'm so glad Jeff finally brought back the ignore thread option.

Again, just my opinion.
