From this reddit thread we have this dirt on G:
They stole search from RankDex, gmail was in beta for 8 years and the search still sucks balls, google maps is allright, android was acquired by them and is still in beta (not officially, but have you seen the problems they’re having?), chrome started out promising but gets worse and worse, Google voice was a neat idea that was stillborn and their mismanagement of G+ and hangouts is legendary. Reader, iGoogle, Google Talk, Google Health, Knol, Picnik, Buzz, Wave, aardvark, notebook, dictionary, dodgeball, jaiku, lively, pagecreator, answers, Google Plus, Google Glass, Google Nexus Q, etc. etc. etc. There’s more dead projects than live ones.
