Heard of Cuil? I did, but it appears that they may have made some mistakes in their launch. This article from TechCrunch details how not to launch a new website.
Check it out. From what I can make out, and it's hard to make out anything clearly, this is a simple case of over-promise and under-deliver. I tried my standard search of "pearl jam" and there was nothing there! That won't do it. Sorry.
Maybe they can recover, but we may have seen the lifecycle of a company already launch and flame-out in less than 24 hrs. That might be a record. I wonder how their VC's are feeling?
I won't throw the dirt on them yet, but we shall see what happens.
