The group of mods running the show now seem to me good people and having seen how they operate I'd be impressed if other city subs of this size are doing a far better job.
I realized after writing the above that it was likely an older word than that, but it hadn't really been a growing memey word in the sub before last year that I had noticed. Maybe the year before? Time flies.
And thanks for the note on the Portland Police Bureau. Too late to update my post, but I'll try to remember that one.
Since the concept of a city subreddit is so obviously pointless, the only people who stay are the ones who like the conflict, exacerbating the problem; or in worse cases like the Canada subreddit, there is a hostile takeover by one side. If you want to talk to people who happen to live nearby, I think you should do so on a different website; reddit doesn't work at all for that usecase.
EDIT: just noticed you mentioned "liberal city", so if it's political stances you're referring to then yes a more conservative-leaning person may not feel welcome on r/portland
funnily enough, I'm referring to the sub often times having a more conservative audience, often coming in from the suburbs (Vancouver being a big one there).
but, "criddler" is much older on the sub than "last year", it's been a mainstay for at least 10 years. and Portland doesn't have a police department, they have a police bureau (sorry, that one's a pet peeve).
