Besides search, GMAIL (sort of...) and Google Maps, what has Google done that has been successful. Even Google Maps and GMAIL are distant 2nd or 3rd in their categories. Most of their non-search efforts have failed - or at least haven't done a hell of a lot. Lively dead. Picasa forgotten. Google Apps...trying hard but no significant share. All their other experiments? Intersting toys. Perhaps this is why their stock deserves to be $250/share instead of $500/share like it was earlier this year. Search is a KILLER business but eventually Microsoft or someone else will make progress and catch up with them. The 'switching cost' for a search engine is zero.
