[FORUM] How has your social network usage changed over time?

[rfmcdpei]

I began my online presence on Usenet, but my first participation in formal social networks. began here on Livejournal. I've remained on Livejournal, but since then there have been migrations, of blog content to WordPress (secondarily to Dreamwidth) and of everything to Facebook. There's some specialty networks I take part in at a low level--Flickr and Tumblr for photos, Goodreads for books, Yelp! for reviews of restaurants and stores, Quora for debate--but that's it.

You?
