Very good advise! "don't spend your Voting Mana on comments if you are not sure you can go over the threshold."
Also I read today that the minimum upvote should be backed up by 5 sp. So if you have only that in your wallet, it is pointless to split the votes.
With 10 SP you can do 50% votes... and so on.
And of course great excuse to put a cool photo and use a proper tag! :)
had no idea about 5sp rule.
It was introduced with the HF now I think.
