Yo Rails! – A Tagged Repository of Quality Rails Links
Yo Rails! is a new site that makes it easy to find quality Rails links (to tutorials, screencasts, resource sites, etc) simply by narrowing down what you want by tags. It was developed because finding certain items again using Google can prove tricky, but by narrowing down by tags, it only takes a few clicks.
It's only a proof of concept at this point, and a lot more resources need to be added, but if this interface continues to prove effective, it could be rolled out to other areas quickly (think Merb, Ruby, other languages, and so forth).
