Here’s a hint:
If you put this link on your weblog: reversible.org/weblogs [delinked to avoid corrupting the index when R comes back], and then click on it at least once, your weblog will show up in the brand new weblogs category at Reversible. Do you get it? That’s what he meant when he said it’s a bit like a directory, and a bit like a Wiki. Anybody can create any category they want (I created /weblogs/) and can associate any site they control with it. I like it.
Here’s somebody else trying to use Reversible in another way: Polls.
