Wikipedia is useful for looking up technical info that there is no conflict over. It is not a good source for diving into a top-level controversial topic as those articles are long and have many places for people to stump and push for their ideas. The more specific a topic (think, a specific author associated with an ideology vs. the page for the ideology) the better. I think I've just adopted these mental heuristics…
> Wikipedia is useful for looking up technical info that there is no conflict over. Even this isn't true. As a former contributor to the Linux desktop community, false information about projects and codebases I had runs rampant on Wikipedia. One Wikipedia editor with more time on his hands than any of us [0] devotes his time to maintaining those articles, despite self-admittedly having little topical knowledge [1]. T…
I had trouble editing technical topics I was familiar with, too, and found it incredibly aggravating. I'd write demonstrably true, helpful, factual content about something only to have it struck for lack of sourcing.
It took awhile to get through my head the model of the project, which included as a basic premise that I, as an editor, am not a valid source. I came to the project knowing that, of course, but didn't realize viscerally how much of the technical writing I do implicitly relied on my own experience and understanding as a sort of "source".
On articles that WP'ians pay attention to, you won't get away with doing that. You'll have to tie claims to a secondary source (you usually can't just point to source code, because then you're doing interpretation, which is a form of original research) both for the claim itself and, sometimes, for the noteworthiness of the claim.
The best way to metabolize this is to realize that Wikipedia isn't the Hitchhiker's Guide; it's an encyclopedia, which means the project has explicitly opted-in to some limitations as a tradeoff to accomplish other things.
(Some articles also just have possessive editors; there is dysfunction everywhere, and WP is no exception).
