I got an account on Metafilter back in '08 and closed it in '15 because it became devastatingly political. It was like a cliff face, it went from a generous and unrestrained community to total one-sided 'my way or no way' politics. I asked the mods to close my account in 2015 because of it and they did.. without the awkward twang of displeasure or faint remorse I was expecting.
To this day, if I see that black and white attitude to politics, I ditch the site. It's not worth it. HN's tech focus really is a saving grace.
When she says "A lot of people left because the site changed and they didn’t", it was definitely my outcome.
BTW this was the best non-professional song I found on Mefi back in '08 (a million years ago?) https://music.metafilter.com/902/Miss-Me-in-the-Morning
