I'm not sure that "interesting specifically to this community" is quite what I'm trying to point at. Taking some of my posts as examples: I want to discourage linking to things like pi.py which might be of general interest to programmers, but not of interest to this community beyond the fact that many of us are programmers. A scream of swifties is more marginal, because swifties feel kind of ingroupy. The sally-anne fallacy is totally relevant.

I'm not sure how to feel about political links.
