Often when answering a question it is useful to point the OP towards another question or answer for more information on a particular topic.
I often see such questions and/or answers come up that I think would be useful to reference in the future. However when the time comes to reference a particular post I often can't find it due to the quite miserably pathetic search capabilities of SE. Currently I try to solve this problem by favoriting the questions when they come up. But that doesn't really work well as now my favorites are getting rather large.
So to solve this problem I propose that we start a community wiki post on meta where we list and categorize useful questions/answers that could be used as reference. What are your thoughts?
