There have been a couple of times where I've felt it could be useful to share information that doesn't necessarily fit into a QA format, and I'm wondering where I could put this on the site, if it's relevant enough to put here at all. For example:
In a recent answer involving data sources, I copied a small list of links to government statistical agencies and central banks that often compile data; it's relevant to the question, but I've answered other questions that could benefit from similar information.
I've seen a few questions, similar to this one asking about financial statements. I recently found that the Wikipedia page of S&P500 components contains links, for every company, to their financial statements in EDGAR. I find this very useful.
Currently, these are my only specific examples, but is there a place where general, potentially useful information like this could go? The only options I can think of are a) the tag wiki, if a relevant tag exists, b) a self-answered question, although for point 1, I'm not sure what form that would take, if any, or c) the answer to any question where it's relevant.
I shy away from c) because at least with my answers, I tend to update them as time goes by with newer links, charts, etc. so I can see some of them falling out of sync. Alternatively, these two examples may not be great examples of general information that should be maintained anywhere and is best ignored for the time being.
