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.
the 500 comment limit made the concept of daily threads replacing common questions a killer on subs like r/fitness. βHas 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.β Just genuinely became unusable.
