WordPress bloggers, could you help a newb out?

I’m a complete newb on WordPress blogs. Despite that, I already have four blog posts up. I find the interface to be maddening; not user-intuitive at all. I tried Googling "how to use WordPress blogs" and I tried looking for a FAQ on WordPress with no luck except that I did notice one thing. The help that is available seems to be all geared towards helping users with the WordPress software they’ve downloaded. I never downloaded any software and, if I can avoid it, I’d rather not. But maybe that’s silly and stupid on my part. It’s certainly no fun trying to put together blogs just using the tools on the site, particularly as there are no instructions for doing it that way.

Any non-trolly input is welcome. Trolls will simply be ignored. ;-p
