m0useanswered grow question a month ago This was part of a smaller roll out and does not function well. They did a massive update in Jan 24' and it fucked the site bad. they made a mini blog post about it and people chimed in what was wong but they said most if not all of that was fixed and it was not.
This new metric stuff on profile was introduced about 2 month ago. so. aug/sept some time. I think its trying to make the site more fun and interesting for potential users or buyers but yea its broken.
Like Shinsimilla said lot of money goes into ad's, to bad one little adblock browser plugin makes it all null and void. Or some DNS's server block ads as well.
