Gardeners, How Do You Blog?

I'd like to compile a list of tips for gardeners who want to start blogging. I know plenty about Blogger but not much about the other blogging services and software out there. What do you use, and why? Are there any particular advantages for gardeners? (for instance, is it easier to upload photos or categorize posts by subject, something that Blogger--ahem--does not offer?)

Let me know how your blog garden grows. Meanwhile, I'm off to the Northwest Flower & Garden Show in Seattle. Oooooh....if you're anywhere in the area, don't miss it. Really, it's extraordinary. And if you want to say hello, here's a list of my worm composting workshops.
