What kinds of things from reddit would you like to see Lemmy avoid as the user base grows?
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.
One thing that I think would be interesting would be a small change to the upvote downvote system. Instead of just showing the total upvote -downvote, you could instead have a percentage, say as a pie chart. That way a user could visually see how agreeable/disagreeable a controversial topic is, instead of just + and - karma.
