I think it's actually not a bad review of us if you filter the anger out. The only part of their post that actually stung was the bit about spellcheck, because it's not done. I wanted to have it finished for launch, but we felt it wasn't worth delaying for. But, we've rolled out two new versions so far today and we're gonna keep iterating fast.
The post also reminds me of this classic Kathy Sierra graphic: http://headrush.typepad.com/photos/uncategorized/loveandhate_1.jpg These guys are talking about how much we suck, and around the world a blogger in France said "je dois dire que je suis seduis par la legerete du systeme." My French is poor, but I'm pretty sure that's "I must say I was seduced by the system's simplicity." This beats a collective shrug any day.
In a domain where the correct thing to do is launch something easy to make fun of, it's easy to sound clever by making fun of things that have just launched. I wonder if the anonymous geniuses behind uncov ever consciously thought about that.
