I noticed a couple of blog posts written in response to my (somewhat) recent php|arch article:
Although this is not a very useful rebuttal, about all I can say is that the EAV method has worked well for me. As with anything, your mileage may vary. I'm not running reddit or facebook, and the systems I've built on EAV don't have thousands of simultaneous users. So I really can't say how well it would perform in a large-scale deployment.
After I sort of got over being defensive about the whole thing, I'm just glad that people found the article interesting enough to talk about it.
