not all +1's are equal. When Dan gives it, it means something. When a freshy does, not as much. Maybe only people who reach a certain level should be able to.
Disagree. Alot of times the +/- is about an experience, nothing to do with how much experience the person has per se, or what "expert level" he is.
For example, saying I did/didn't get an Amex Sync email and I did/didn't get credit. Or when your points posted. That is a simple fact/data point which often helps people, and yet wouldn't necessarily have any correlation with being a noob/veteran.
What would be ideal would be to split up these two types of thumbs up, I.E, opinion vs. data point. But then again if your following the thread, I guess its pretty self explanatory which one it is..
