This board is as close to "social networking" as I get.
In fact, my ten year old son has taken to asking me "Dad, are you on your Man Facebook again?" I'm not sure where he got that phrase, but I think it's because he sees his mom and sister on Facebook all the time, and assumes TrekBBS is my version of it.
I don't have a Facebook page or twitter account. I'm not on LinkedIn or any of that.
^This. I only have three or four people I would consider friends and my family contact me directly. I'm not a social person, so this site is all the "socializing" I'm likely to do.
