Takes 10 - 20 minutes to generate screen shots using various browsers.... I bet the Lifehacker posting caused a jump in usage...

While I do like the idea of a utility like this, I find it much more reliable to have multiple browsers installed on my dev machine to view sites myself instead of relying on someone elses service.

I find that having multiple IE's installed ( I have 3.0 through 7), FF 2, Safari 3 Beta, Netscape, and Opera and testing myself, solves 99% of my browser incompatability issues.

Not saying it isn't a great tool, it is. I just find that doing things myself makes me sleep better at night.

It took 45 minutes for it to do one of my sites. (ouch!)
