You're not alone. I realised that Facebook makes it possible for completely non-computery people to share pictures, write notes, have on-line conversations, have a sort-of blog, all in a one-stop shop. When my older niece started to use it I realised that there were half a dozen other facilities that would serve her better, but it's the 80/20 rule. For essentially zero effort she got more than she otherwise could have.
I sigh, but it's the way it is. It's the way it was with AOL, and maybe something will kill it eventually, but it's the way it is now.
I look forward to seeing where it will go, and I hope it's better than anything we can currently imagine.
It probably will.
