I spent a day in the official Reddit app, and it was miserable. So far I really like Lemmy, the content is much richer than I anticipated, and Sync makes me feel right at home, and the ads aren't too obtrusive (unlike the fucking Reddit app, Christ it's miserable) I think 20 for the equivalent-ish to pro is fair, but I am from a wealthier country, so my reference may be different to others. Ultra seems steep to me as well, but it's still way less than the official Reddit app lol.
So glad for the work you're doing, and excited for a new chapter of happy doomscrolling and community-building.
