It encourages you to post, it's feedback. Most people like to believe that they are talking to someone and it also lets you know that there may be many lurkers reading the board and not just the few that post.
Also , like "Facts..." said earlier it would be preferable to only count once per visit and not allow it to be triggered by someone with their finger on refresh
Why in the H-E double hockey sticks do we have to click on the Bullish or Bearish button EACH and EVERY time we post.
If I use my 15 free daily posts that's 15 unnecessary clicks EVERY SINGLE DAY.
Shouldn't there be an option where you can have it set PERMANENTLY until you decide to change your sentiment?
People's sentiment don't change with every post. Lol.
ALSO, I've noticed less and less people clicking on their sentiment since the initial release because it's become a HASSLE to click on one of the buttons EVERY single time you post.
