Honestly, I don’t like it. Nothing personal, it’s just my opinion. I think it devalues new members who come on here and ask questions. In my eyes, the people asking questions are just as important as the people answering them. Without questions, there can never be answers for the elite few to max out their star count. Not everyone knows things, many are just beginners starting from scratch who will never be able to build up a star count.
I think a karma system would be better, where replies can be either up or down voted or ignored completely leaving users with positive or negative karma.
