yeah, we have plenty of services from Google. Like gmail, analytics, orkut, blogger ( though they are bought by google) Among them what is your favorite? Or what do you felt as the best in google? I think it is just their search engine.
Any talk of Web 2.0 era is not going to complete without Google. There are many myriad applications that Google has developed over the year. I basically like Google earth, Google docs and spreadsheets.
