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.

Defederation works against that though. When I first joined a few weeks ago, a lot of the discussion was taking place on Beehaw. I joined a few communities over there and started to enjoy the experience but in an instant, all of that was blocked because Beehaw decided to defederate from Lemmy.World (and others). That sort of thing will happen more and more in the future. I don't want to have to create a dozen different accounts on a dozen different instances to view the content I want to see: I want a simple interface with everything in one spot.

Reddit offers the "everything in one spot" piece, but they killed the simple interface possible via apps like RIF and replaced it with an abysmal official app.

Lemmy offers the "simple interface" piece with apps like Jerboa, but the federation aspect of it makes it hard to get everything in one spot.

The second a competitor offers both features with a large enough community to allow for meaningful discussion, I'd be happy to make the switch.

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.

In what context?

In the insurance world, you sometimes see the phrase "L+ALAE Ratio" to refer to the ratio of (losses + expenses) divided by premium. It's a way to measure profitability for a book of insurance business: how many dollars of loss and expense do you have to pay per dollar of premium earned? Lower is better, and you don't want that ratio too much higher than 100%, because that means premiums aren't high enough to cover losses (though investment income can sustain small underwriting losses).

I could see "L+" used as shorthand for "L+ALAE" or "L+ALAE+ULAE," though admittedly, I've never seen that specific shorthand used.

Open Street Map is legitimate. In bicycling communities, Strava is the gold standard app for tracking rides, and it uses Open Street Maps on the backend. It's always super accurate for me, even for fairly obscure bike trails off the beaten path.

Ahh, the word "hor." Can't let the children see such profanity.

Gotta love when ~~classic~~ cl***ic profanity filters are implemented without learning the mistakes that have been made again and again over the last 30 years.

Agreed. Something like Top for the last 4 hours would be super easy to implement because Top for the last day already exists (just change 24 hours to 4 hours in the code that fetches comments). However, for those that are used to checking the site multiple times in a day, you don't want to ge served up the same content every time you check. Top for the past 4 hours would seemingly be a decent balance between giving posts that have some type of traction while not giving posts that are stale.

I think it's because a few of the posts appear at the top for everyone, so people keep adding comments to those, which "bumps" them to the top of the feed like it used to work with forums back in their heyday 15-20 years ago.

Agree that it shouldn't be so complicated. I see that as a major flaw of the platform that will curtail adoption, but who knows, maybe one will win out over the others?

In any case, my understanding is that you can't log into the other instances with your username from lemmy.one, but you can read posts and interact with communities on different lemmy sites. For instance, I'm commenting from lemmy.world on a post you made using lemmy.one at a community hosted on lemmy.ml, but we can both read each other's comments, and so can people that signed up on other instances like beehaw.org.

Depends where you go. For instance, the discussions in AskLemmy seem better than the discussions in AskReddit right now, but lots of communities are basically empty still. The main baseball community on Lemmy.ml only has a few highlight videos posted, pretty much all from the same user. The corresponding Reddit feed would be much more active with both posts and highlights. It'll take a bit of time before enough people migrate over to start posting content again.
