I have found ehow to be as reliable (if not more) than Wikipedia for the searches I run into it. I use it quite often when some new task comes up to figure out how to do a task. I even made a custum search default for eHow. I think the quality of articles is better than what is generally available on the web. For every rare low quality article you can find on ehow – you can two dozen on wikipedia.
The downside to this for me is that it re-enforces the myth that all it takes is content to win in the search engines. Sorry, I no longer believe quality content = quality rankings. That dream has been dying for quite a few years (along with everyones traffic and rankings in Google as competition makes roi on seo an unsustainable endeavor).
What Rosenblatt and the crew have done is nothing short of genius in the SEO space. To qualify algorithmically and engineer daily content is freaking brilliant. To get it to rank and convert in the long tail is even bigger. No wonder everyone is so jealous of their success. They are the top SEO’s on the web. They are without a peer.
