I like the idea a lot. I think it would be great to have an information aggregator for kitchen knives and other blade-related info.
I actually started collecting links on delicious (even though that site is dying). I'll have to transfer them to another platform in the near future. Anyhow, I was frustrated with forum search engines and how information is so easily buried in threads. Now that the kitchen knife world is fractured, I will start using it even more.
With that said, A good CMS website like that would be very valuable, especially if they highlight hot topics and new information. Sort of like a Food News Journal for kitchen knives.
