I’m going to bite on the issue of Google overvaluing posts on weblogs in its index. I think it’s a problem, but it’s not a huge problem. I look through my referrer log every now and then and see what sorts of hits I’m getting from Google (and I do get a bunch of hits that way), and in nearly every case my item has a link to something that the person who typed the query was probably looking for. In those cases, I think that items on this site are adding value to the index rather than muddling it. There’s also the unseen advantage of weblogs helping to set the value of other pages in the index. It may call for some adjustment to Google’s indexing algorithm, but I don’t think it’s really worth getting worked up over.
