It's pretty simple, happens all the time. In order to get big you have to sacrifice the community.
Back in the day VG Chartz was more of a family, there wasn't that many people, everyone was close, ioi posted funny stuff, the mods or admins had fun from time to time with threads messing with people. Everyone heavely favoured one video game company and everyone knew what it was. Basically once ioi quit his job to run VG Chartz and it stopped being a fun hobby and everything took a serious turn, which is fine it makes perfect sense for ioi, who wouldn't wanna run there own website at home as a job, doing what they love.
Now you got tons of new members, old members leaving and the ones that didn't leave just bitch about it. The mods have to be more professional about there job, same as ioi everything just got serious...where's the joker when you need him.
