I'm a bit of a blog addict - My RSS Reader has about 20 sex blogs of varying styles in it, and I've got another half-dozen or so that don't have RSS feeds so I check them less frequently.
Been toying with the idea of starting a blog of my own, but have never gotten around to it.

...and I just rescanned the forum rules and couldn't actually find anything that banned posting links, so I'll give a couple.
I don't have too many femdom blogs, and my favourite is Mistress Matisse, but another fun one is The Enchanted Palms. Not so much a day to day events blog as a theoretical and philosophical aspects blog. Interesting reading.

I'd love to share some more of my favourites, but I think I'll wait, make sure nobody comes around and says not to post links, and then make a second post.
