As for the ages here, the people most likely to migrate are the long term Reddit users that have had an account using third party apps since 2010 or so (because younger people have only ever known the official app). That self selects for anyone that was old enough to use Reddit in 2010 back when the user base was mostly high school / college / recent college grads. Someone in their late teens / early 20s back then will be in their 30s now.

Stress is relative to your own personal conditions. It’s not absolute. A tech executive might have a nice house and financial security, but if he’s working 80 hours/week under intense pressure to meet some deadline, that’s still stressful. Nobody wants to be perceived as a failure at work, even if their personal financial consequences for failure are minimal.

Your argument seems to imply it’s impossible to feel stress if you’re comfortable in life. Even the poorest Americans can count on access to food, clean running water, electricity, internet, etc. For most of humanity’s existence, and still today in some parts of the world, these would be considered enormous luxuries, so anyone with access to them would be seen as extremely comfortable in life. Clearly though, people can still be stressed out despite having access to these sorts of things that most of history would consider luxurious.

Stress is relative, not absolute.

Why? You should let each post stand on it’s own merit.

First, account age is silly for Lemmy, as almost 100% of people on here will have an account creation date in June 2023 or later because this place was a ghost town before Reddit decided to kill the APIs. A month from now, is someone with an August 2023 join date automatically presumed to be a troll, or are they just someone making the switch from Reddit a month later than everyone else?

As for karma, neither negative karma nor positive karma really tell you anything about the poster:

For instance, people can make good faith arguments advocating for conservative political opinions, but because the user base skews pretty far left here, those arguments will be downvoted. A discussion forum that bans opposing viewpoints is useless, and the echo chambers on Reddit are something I’d love to avoid here.

Similarly, it’s also possible to effortlessly build positive karma. Simply copy/paste highly rated comments from the last time a common repost appeared on the feed, and chances are, your copy/pasted comments will get upvoted too. You can even automate it with a bot.

Karma meant nothing at Reddit, and moderators shouldn’t be using it for decisionmaking purposes. It’s useful for ranking posts and comments, but anything beyond that isn’t helpful.
