I voted positive - I don't like Google simply because I don't like to any one company get so big... (eg: look at Microsoft, Walmart, etc. It seems like certain things go with that territory) and that all your information is stored in one big, convenient place for Big Brother (I'm weird about that stuff after reading Mitnick's book and all those news items about 'lost' laptops, blah blah) - albeit Google is the only search I ever use... does that make me a hypocrite? 😱
However, I say it's positive based on the fact that so far Google seems to be alright; They make a good product, it's all free (er, mostly), and really they've built their success in the face of the (at the time) giants in the field to do it their own way and make it work, and that the perceived value they've attained is amazing: eBay, Amazon, they're tangible because they sell physicial items - but Google has succeeded in building a HUGE company based almost entirely around information and intangibles.
