good points! I'll add the commenting should bring any value to the community or enhance the original post. I read posts and if i sure that's a topic that touches me and have my own experiences which may be valuable to others then i got the urge to share it and i'm glad to get some feedback or maybe an upvote. But bringing value to others seems to me always essential either with my own post or by commenting others. Sometimes i had a longer comment than the original was because i feeled it's worth nethertheless i got an upvote. Thanks for the reminder!
