I can see the value in something like this, especially for more novice web developers who may not know the terms to search for in Google or StackOverflow to find what they need.
I understand it's rough, but here are something of the things I was expecting to see while I was browsing around:
- Some "category" pages, like dbm, are missing definitions. It would be great if definitions were present on every category page.
- I really like that some category pages include a curated list of articles that compare the different options within this class of products. This is exactly what I search for when researching new technologies.
- It'd be nice to have links to the Stackoverflow "tag" page on individual technology pages. For example, the MySQL page could link to this: http://stackoverflow.com/questions/tagged/mysql
I could also see this information being shown in a more visual way. It'd be pretty interesting to allow companies to create an account and build a profile of what their web stack looks like. Maybe something similar to how GuitarGeek.com shows the rigs of famous guitarists? I'd be willing to bet that most web stacks would look more like Eddie Van Halen's setup (http://guitargeek.com/rigview/258/) rather than Angus Young's (http://guitargeek.com/rigview/312/) :)
