One thing I have noticed in the aftermath of this decision (which I wholeheartedly support) is that it becomes even more important that people properly mark helpful and correct answers to questions. I get lots of likes to answers, even from the original poster, when a helpful or correct answer would be more appropriate. I've also noticed that related, and sometimes unrelated, questions get asked in comments and answers to those can only be rewarded by likes since only the OP can award helpful or correct answers. These answers no longer earn you points.
I wonder if we need to find a way to encourage more awarding of helpful or correct answers? And if anyone has any suggestions for how to deal with the "related questions" problem...
I'm not especially driven by the need to accumulate points, but if the points system is meant to encourage people to contribute obviously some people are so motivated and the points system needs to work properly.
