I disagree, why take away a system meant to reward people for being insightful?
Because it hurts the community at large. The TP love fests cause the cliques and pageantry that people are pointing at as causing issues on the site. The behavior it's been causing is juvenile.
People may not agree, which is fine. But consider this - how is a karma system community building when 1) there is not negative karma to bring people back to Earth and 2) people who invest a lot of time/energy/thought writing their thoughts, which may not be "popular", do not receive this "reward" for their contribution?
I just don't think it's healthy for building a "community" - if that's the end game.
Just one man's opinion.
