When I am looking for a nugget of wisdom for wisdom's sake (as opposed to dealing with a particular problem in front of me), many times I will turn to Tutorials, Best Nodes or Selected Best Nodes, or once in a while, the Q&A section. I suspect, however, that what you have in mind may be something a bit different...
Actually, now that I think about it (doesn't that always seem to happen after hitting "create" or "update"), perhaps the keyword tagging mechanism for nodes (which I haven't looked at much) might be a way to do what it sounds like you have in mind?
