domain hunting

sometimes i like to think up some (what i think are) really cool sounding names for a concept, company or thing and then rush to a domain search site and see if it is available.
sometimes i feel really happy with myself when i see that the name is available (atleast was at the time of this posting) and no one else thought about it first! but othertimes, i am amazed too, but not just the fact that someone else came up with the name first, but with what they have gone and done with it!
