I believe its just a matter of time before all of the search engines will be bought by google and google will control the internet :-P Of course there will be rebels and all but they will dominate. the thing to do with Google though is figure out when it goes down. most of the time the stock will go down before big holidays (valentine's day being an example, it went down 3 dollars because people wanted to buy their woman flowers).
Anyways I think the way to go is to play it like forex, scalp it. Sadly I would probably never do it due to its extremely high price
