In response to various emails and other neurotic queries, yes, I quit Twitter. Why? Because it was my crack, and I had to put down the pipe. Because it was a time suck. Because I felt like it. Please cease sending me your stricken, mortified emails regarding the absence of my inane comments, random links, and other drivel from your lives. I remain unmoved.
Basically, I needed to spend less time doing that crap, and more time working on my novel. You are aware that I have a full-time job, as well? Or, perhaps you were not. And Twitter as a gig doesn't pay well, unless you are a Kardashian.
I'm sure I'll start up again in some other way when I get obsessed about some other thing.
