I don't think the site is dying.
The deppo banning was unnecessary and we lost (well apparently he's gone) a decent poster. I feared that as a result of that the site could go downhill.
However, a number of people who previously did not post had something to say. I've noticed a number of posts recently from people who I've never previously noticed.
For someone like me who on the whole would rather read than get involved, this is still a decent site.
The one thing that has made the site less interesting is the lack of genuine itk people giving us the heads up on football matters. I suspect that has more to do with the club doing it's business in private rather than anything else though.
