Sweet! Morons.

The problem with SiteFinder was that Verisign took advantage of their central position on the internet to make a change to it which benefitted them, but that change forced everyone else to make changes to accomidate them. They helped themselves and hurt everyone else. Google Accelerator is similar. Its more useful then Sitefinder, and Google has less "lock in" as a central net figure then Verisign, but unless this thing dies a firey death in the next few days every webmaster in the world who runs something more complex then a personal homepage is going to have to make changes to accomidate it.
