Kevin Marks suggests using BlogTags to make topics "emerge" from the wild wild-web. The idea is neat. Simply insert a WikiWord (that is unlikely to get confused with a normal word, because it is at least two words smushed together) into your blog entry, or web content.
Then, when others want to find links on this topic, they use the same WikiWord in their favorite search engine. The search will have both high recall and high precision! Great idea!
