I've blogged casually off and on, have deleted some, deleted my LiveJournal account, have used Blogger and Wordpress. I'm not consistent with it.
And one of them started out as the "writer's blog" so many newbie writers are told to maintain, as part of "platform" or whatever. Even as I started that it didn't make sense to me - "why would anyone want to know what
I think about writing? I'm a nobody!" That one dried up quickly.
I originally started blogging as a way to keep long-distance family and friends in touch with what was going on with me and my family, but then Facebook kinda took that over.
Last fall I decided to start a new blog about random things I find interesting. I took a class in winter term, though, that had me in fits, and between that and working full time, didn't manage to write anything for it. But I think I'll start, just for myself.
Anyway, here's what Chuck Wendig said recently about blogging:
"You want my blogging advice?
I give you my blogging advice.
DON’T BLOG!
There it is. That’s my advice to you. Don’t blog. Don’t do it. Not worth it. You’re probably asking me as a writer, and as a writer to another writer I say: mmmnope, f*** it. Don’t blog.
<snip>
And finally you’re saying, But I wanna blog, too.
Well, okay, then.
Then it’s time for a different set of advisory points.
FINE, YOU’RE GOING TO BLOG ANYWAY
Welcome to Der Bloggerhaus. Here is your blog.

Your blog is you. It should echo your voice. It should demonstrate who you are and what you believe — a larger, more direct version of the voice people will get inside your books. This blog and my books do not sound exactly alike, nor should they. But both, hopefully, sound like me. And your blog and your books should sound like you."

So, blog or no? If it's fun or useful for you, then yep. If not, then nope. That seems to be how most advice has shaken out after a few years of "everyone must blog!"
