I want to crawl into a cave and never come out

If you're reading this, you obviously know I have a blog (duh!).  I also have a Twitter account (which I don't know how to use), and this past weekend I created a Facebook Author Page.  I believe that all this stuff is important, especially for a soon-to-be published unknown like me, so I'm making the effort to put myself out there.  All for the sake of my book, and for what I sincerely hope will be a long writing career.

But I'd be lying if I said I didn't kinda sorta totally hate it feel just a little uneasy.  It's hard not feel exposed.

In my dream world, I've got a bestselling novel (or twenty) and nobody knows anything about me, except for the books I've written.  Unfortunately, that's not reality.  As a reader, I'm always disappointed when authors have no web presence, because when I'm moved by their work, I crave personal tidbits about them.  Where do they live?  Are they married?  Kids?  Pets?  Are they nice or are they assholes?  If I like their books, none of this should matter... but somehow, it does.

So I forge ahead with all this self-promotion stuff, feeling completely uncomfortable, a little bit naked, and wondering what the hell I've gotten myself into.

What would you be willing to do to promote your book?
