Manufacturing Serendipity...
We talk about using personal blogs to network -- but the term "network" leaves an unpleasant taste in some peoples' mouths. Does it conjure up salesmen or politicians for you?
Jon Udell calls the effect "manufactured serendipity" instead. Last time I took biology was in 9th grade but it's kind of like using your blog to put out little feelers which can touch another blogger's feelers via trackback, technorati, and other search alerts.
