Yeah, could totally be a regional difference.
I had the same thing when negotiating for salaries too, so it wasn't just when talking to people, but it was in a more official way as well, and I even got it in my contract like that.
When I was working as a tutor, my contract listed my pay in hourly pay, because I worked varying hours and I was paid by the hour. On my entry-level job my contract was in monthly before-tax pay, but negotiations were with monthly after-tax pay. And my later jobs were all in yearly before-tax pay, which might also have been relevant that way because in some of these jobs I had yearly bonuses and/or part of the payment in stock I got once a year. So with these yearly figures in there, probably it just made sense make everything yearly.
This.
Just from the features and the convenience, Reddit is better. It's bigger, it's got more content, it's easier, it's more stable (or at least used to be). You don't have to worry about your instance going under or anything like that.
The reason for the devs to invest their time to make lemmy and the apps and for admins to invest money and time into hosting and running the instances and for users to use this instead of Reddit is mainly the politics of wanting to have your own space with your own data.
