Slate has a piece by a blogger who decided to shut her blog.
Blogging had been the ideal run-up to a novel, but it had also become a major distraction. I would sit down to start on my novel only to come up with five different blog entries. I thought of them as a little something-something to whet the palate—because it was easier, more immediately satisfying, because I could write it, and post it, and people would say nice things about it, and I could go to bed feeling satisfied. But then I would wake feeling less than accomplished because a blog wasn't a whole story told from beginning to end. I had shelves lined with other people's prose while my best efforts were buried on a Web site somewhere, underneath a lot of blah-blah about American Idol and my kitty cat.
She's absolutely right about what's cool about blogging, but, personally, I'm not sure it isn't wishful thinking to imagine that if you don't blog, you're suddenly going to start writing a novel. Maybe it'll work for her, but if I've learned anything about this stuff over the past year, it's that blog posts aren't the same as pages in a book that has a plot. For me it wasn't fungible -- in fact, the less blog I wrote, the less novel I seemed to write, because the blog was helping me get the words going and I found it nice to have that alternate outlet at the same time. It wasn't all fungible -- it's not like saying you'll sleep more if you don't take a nap in the middle of the day (I'm guessing that's true, although maybe sleep doesn't work that way either). But I don't necessarily expect it works for every book the same way it worked for mine, and that everyone writes the same way, so if she thinks ending her blog will help her novel, cool, I hope it does. I just thought the piece was interesting enough to link to -- I don't really have strong feelings about it, just wanted to pass along the link.
