If not, I think you should write a NF book on Social Media for Writers. I think a lot of people would find it very helpful (and it would probably sell really well, too). And I have to commend you anyway on somehow managing to maintain a regular blog, a Tumblr, a Twitter, a FB, a job at CNet, a mod position at your own forum and completing a book, not to mention whatever else is yours to do during the day. (I wish I could live in SF, too, because if Scott McKenzie is right, there are lots of gentle people there.)
I figured since this was the Ask Nathan board that I'd "query" your opinion on the matter.
And of course, the burning question is, how do you do it?
