Yeah, I know about Ruby Toolbox. It's a good start, but all it really tells you about the possible solutions is their relative popularity. I'd like to be able to look at a more contentious category, like Background Jobs, and see some detailed reasons on what the trade-offs are between Resque, Delayed Job, Sidekiq, etc so I can more easily make an informed decision about which one to use.

Seems like a good solution for a website, as you'd be able to keep those expert opinions in a particular place for people to go to, rather than having to search around on SO, forums, and IRC sites for this kind of info.

While I've got the idea hat on, label it with the version of everything mentioned, so you know when the info might be out of date.
