Chris Pirillo disabled anonymous comments in early July. At some point, he re-enabled them. I guess I'll be visiting his blog more. When I posted about this, I mentioned that I'd be turning trackback back on to see if any got thru. I think a couple did, but not enough and I turned it back off.
Around the same time Scoble was talking about a new killer app that would replace comments. That turned out to be Memeorandum. Memeorandum has had a changing affect on the blogosphere, but it doesn't replace comments. Mostly Memerandum has ensured that everybody is blogging about the same 3-4 subjects everyday.
