Well, personally, I'll be interested to see what this website has to offer. While it's true gamelists and forums are pretty much taken care of, there are perhaps other things that a website could do, such as hosting game walkthroughs and reviews (audio or text), listing stuff about other forms of accessible Pc games such as interactive fiction, online text rpg's, and gamebooks, anything about accessible main stream games, that type of thing.
Even if it is just a replication of what's on audiogames.net and Pcs, for google search engines and stuff it's never bad to have more publicity, ------ though constructing and maintaining a gamelist at the same level as Audiogames.net and Pcs might be quite a task.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
