Hmm... I've had a blog for a year or two now. I don't have any particular advice. I've noticed that I prefer Blogger over Wordpress. Blogger is just easier for me to comprehend. But you already chose which sites you were going to use, so never mind that.

With your JoshuaSSandefur blog, the only advice I have would be to post at least someone consistently; I have the problem of posting sporadically, which makes it harder for my followers to know when to check back for a post (unless they check their blog feed every day, which I doubt many of them do).
I don't think it's
as important to post consistently with your writing blog, though it might be nice to if you have the time. I don't think it's as important though, since most people should realize that writing takes time, and you can't have a new piece of writing up at the exact same time each week/month/etcetera.
I'll try to think of more advice. Until then, I wish you the best of luck!
