Unfortunately they have recently taken a rather drastic step towards undermining this community aspect of the site by gating the comment (or "shout", as they call it) box behind a "SEE WHAT OTHERS ARE SAYING BUTTON". Previously the top 5-10 comments would by default be visible on every artist/album/track page, but now there's an extra level of indirection you've go to go through to see or post comments. The move was never justified despite the vocal community's outrage on their forums [1], but I suspect it's got something to do with the site's poor performance, as previously comments failed to load about 30% of the time. Strange, yeah.
I've cancelled my Pro subscription a while ago as a result, but I'm excited to see what their independence from Paramount will bring.
