I gave you an upvote.
I think it’s dangerous to make comments just for karma. Then you will be less likely to take risks.
Karma is nice to have for me. If I post something, and see my karma go up by 10 points, I think “oh that’s nice”, but I don’t then go to “how do I get 20 the next time”? Likewise if it goes down 10 points, I think “wow some people didn’t like my comment, oh well”. In the end my karma is generally trending up, which I take to mean I’m generally adding more than I’m detracting. If it was generally trending down, I might consider if I’m coming across wrong / being misunderstood , or maybe something is wrong with the people here!
Also if you want more karma, just repost old posts that got a lot of votes, like the OP did :D. Likely to at least some votes esp if still relevant.
