Personally I think not having karma limits is nice currently! I understand why they were used but grinding karma as a lurker on reddit was frustrating.
A relatively small thing: the 500-comment viewing limit for normal accounts. So many times on Reddit I’ve been put off engaging with posts with 500+ comments knowing that nobody would see it. It’s stupid because comments are just text and unless the software design is absolutely terrible then simple text comments shouldn’t take up bandwidth at all.
the 500 comment limit made the concept of daily threads replacing common questions a killer on subs like r/fitness. “Has this question been asked before? Well, instead of being able to pull up several threads about this topic, I have to go through the daily threads of hundreds of days and search the comments for keywords - after increasing the number of comments visible from 200 to 500, and then still not being able to search all the comments on the 1000+ comment threads.” Just genuinely became unusable.
