My suggestions:
Make it clear which regions / countries are hard to track. Mention why PS2 data is often added afterwards compared to other sales data if this happens.
Mention sell through sales data from Sony's tracking, Japanese trackers, Chart Track and NPD for comparison of the supplied data in the charts.
Make auto formatted messages a selectable option.
Moderation, act harder against personal attacks (create terms of usage / guide page). But stay open towards criticism and difference of opinions.
Maybe add a special features section, maybe including (staff-user submitted) feature articles such as interviews, reports, tutorials, staff editorials. Exclusive content to attract new visitors due to news coverage from other websites.
