Its all down to reputation people have given you.
If you posted some mindless crap in your first few days/weeks/months of posting, people would have given you negative feedback (look at the scales icon at the bottom of the users details).
It takes an equal amount of positive feedback to cancel out the negative feedback.
Maybe nobody had ever given you user feedback ? If you click on

I remember my first ever feedback was from Krumlink having a strop about something everyone else found funny. Fortunately as he was a new user at that time it didn't really count towards my reputation and he's grown up a lot since
As you get more feedback/reputation, your power to dramatically increase other users reputation also increases.
I.e. a new user giving negative feedback will have little or no effect on your overall rating. An experienced user with lots of positive feedback can instantly bump your feedback to a high level.
I'm just under 450 points on my feedback - I've had a lot of positive rep from newbies so that doesn't count though.
