At first I thought our captcha had been broken and this had to be spam. But after rooting around we decided it wasn't spam, it's real activity. Then I looked at seo but I didn't see any change there. Our best bet now is that it's due to the redesign plus the new site being faster, which has lead to more on-site activity.
An odp editor is picking a bone with my "75k" number of dmoz editors. That's the number on the dmoz homepage. Yeah of course not all of them are active, the site is 9 years old and the number never goes down. Plus they stopped letting anyone new in about 4 years ago. A much more interesting number is the number of daily edits. But in the end it's apples-to-oranges, since dmoz in theory benefits from the previous edits of now-inactive editors, whereas Topix will only benefit from sustained daily editing activity.
Thus it's more interesting for me to say that Topix had 804 editor posting events yesterday, which is a 24% increase from the 645 posting events it had the previous monday. It's hard to predict success with two weeks of data, but of course we want to answer the question -- will Topix become big in its domain like dmoz and wikipedia, or will it moulder with no use like a Backfence. Well at this point it looks like it will become very big. No one will realize it for 1-2 years while it grows though. :)
Our launch party came off quite well last night. We had about 200 people at the St. Regis and I saw a lot of old pals I hadn't connected with in a while. The street teams worked out better than I expected too. I got some good quotage too from the morning panel. My talk tomorrow in front of the whole audience (wow big room) should be fun.
