If you feel that an article or post helps you in finding information, there is nothing more difficult than pressing the [+Karma] button as appreciation. And what's fun is that you can give karma every 10 hours to the same user, as long as the minimum rank requirements have been met, it's actually easier and you will feel that giving karma won't make you lose at all.
I think many people do that too, you can give karma as much as you like, it's just that it's time limited.
Users with the 'Teleported' badge should be able to send karma more often, because in btt to be able to send merit to other people, we have to get merit first to get sMerit.
