Yes, it's counterproductive to do a blog post asking for help when the problem is that most people can't comment on my blog anymore.
If you know how to fix the problem, but can't comment, please email me: firstname.lastname@example.org
I hate Blogger. Thought I'd switch to wordpress, but can't pay for the hosting thingy, and frankly am not up for anything complicated right now.
Update: Brownfemipower told me about the free blogs at Wordpress!
