You can submit your own, categorize it and link to it. You can also do this for your friends, and they probably wouldn’t mind. (I haven’t decided if I’ll dump all the blogs in my sidebar in there or not; at last count I had 89 or so there. I might think that over first. 😐 )
It sounds like he’s planning on managing it much the same way I manage my list — cull through them a month at a time, and make sure they are what they claim to be. You can also report a blog if it doesn’t seem to satisfy you.
I’m interested to see how many new ones pop up. 😉
