I think this site has already helped a lot. I find the interviews and articles hosted here or linked to here not only help to tie together the international DC scene, but also have brought those important to the scene to the forefront, giving official reports as to what they are working on etc.
Other than that, i think something the scene needs a lot would be an updated KOS manual, right now the one hosted by SF is 2 years old and still talks about the TA and such.
We also need more information on sh4 assembly and more libraries ported to the dreamcast, such as allegro and maybe a fake DirectX or something :P
