Why can't I find what I'm looking for online?
On the heels of today's earlier post "Finding Optimal Relevance" Google has released personalized results. The 'one page fits all' model has been replaced with a collective understanding of what you do and possibly who you are in order to improve results.
Not surprising, optimizing for Google tools is recommended. A bit more interesting is "Social Search" - using the searches of others to find results; not unlike collaborative filtering for books.
Maybe I will find that SEM doesn't mean scanning electron microscope.
