After Microsoft decided to slap Yahoo with an offer to buy it, Yahoo seemed to have decided to go crazy and not really wake up, but snap and go crazy with major business changes: merge with AOL and experiment with using Google's adsense in their search results instead of their own. Michael Arrington at TechCrunch suggested that they are using a scorched earth technique to not leave anything behind for Microsoft to get. It's a shame. I can't say I'm a huge fan of Yahoo, but I think they have good products and have been able to create (or purchase and not destroy - which is a huge feat) a system of niches that empowered the internet.
It's going to be sad to see it all go away with this apparently spooked company. Damn you Microsoft! Just use your very capable workforce and get it right!
