A lot of that has to do with the fact that no one is actively adding new content such as news articles, stories and rumors about upcoming technologies here. The site also looks very old and dated and the fact that the newest articles are from 2009 or thereabouts makes it look abandoned and run down.
The site has become the antithesis of leading edge and people want new and fresh and up to date, state of the art, especially in a computer or tech forum.
