Okay, so, in spite of a certain rant three years ago, I am on Facebook, now.
It has significantly improved, I think. Or maybe the avalanche that hit me on attempted signup three years ago was due to my path in.
It's still not half what it ought to be. No, it's well less than that. Social networking is thoroughly hamstrung by the underlying profit motivation. We shouldn't have to write all our social activities on a business ledger.
Why did I join Facebook? Lots of people at church are using it. It is a bit more convenient than e-mail for certain kinds of contact.
Also, I'm beginning to suspect that I should quit trying to put someone else between myself and the student and just open up my own English/eikaiwa school. SNS will help with that.
Bonus -- I found the LDS authors Facebook group, LDS Beta Readers. Look them up if you're on FB and are interested.
