Evan Williams [I lost track of how I came across this post]:
Most of the people who I’ve heard, anectdotely, say that they think blogs sometimes get undue ranking, mention coming across their own blog for searches. They don’t necessarily complain about about coming across other blogs. Could that in part be because: a) They’re using phrases to search that are natural to them (and, therefore, the words they use to write) but that aren’t quite as likely to be used by others as they might think? b) They’re not going to learn anything from their own blog, so they consider that result useless, while another blog’s contents they may find valuable?
This confirms my feeling that weblogs are not at the top of all searches people do. Probably they are at the top of many searches bloggers do 🙂
