Not that I notice these things, but in the past week my Technorati 'authority' (number of other sites linking here in the last 90 days) has dropped like a stone, and my ranking seems to vary by several hundred thousand depending on which way the wind is blowing at the time. Maybe they're all getting a bit overloaded. It looks like links from the sidebars of other blogs (like the ones down the right hand side here) aren't being counted any more.
Technorati are also doing a 'state of the blogosphere' to find out who blogs, why, and how long for. Click the link to take part. Quite a lot of questions, not quite sure I have anything informed to say about blogging and the US election, but there you go - an ignorant opinion counts for as much in the survey as a well-informed one.
