all puppies eventually turn into lame dogs
It certainly feels that way, given that the so-called "Google killers" that we've seen so far (cuil, blekko, et al) are inadequate by almost any definition. But things do change and given the direction that Google has set for itself, it seems to me that the time is ripe for an upstart David to strike the giant Goliath.
That upstart needs a brilliant algo, a viral interface that everyone wants to use, and a ton of storage. The algo could come from a couple/few brainiacs working in a knotty pine basement; the interface simply needs a cutting edge super-talented designer (and there's plenty of them around); and the storage has never been cheaper (those of us who have been online for more than 15 years will remember when the "new" one gigabyte drives came out at $500 each ~ now you can get a gigabyte at Rite-Aide for $9 to put on your keychain. The current terabyte
drives ~ a thousand times more powerful than a GB ~ are only $100, so it's just a matter of time when they'll
be $10 and will fit in your pocket!).
So Google is fair game, and as I said, if they continue spoonfeeding people results that do not measure up to what they delivered a few years ago, they stand on shakey ground. And as everyone knows who has ever stood on shakey ground, it's just a matter of time before you fall. The people at AOL, MySpace, AltaVista, Excite, and yes even Yahoo could speak volumes to that simple truth...
