I just registered DataNostalgia.com with the intent of developing it into a site for retro gaming, old computers & game-systems, and digital memories from the 80's. How would you go about developing this concept? A blog, A forum? a gallery?
for bonus points, what film is this quote from... "Shall.we.play.a.game?"
erm, I personally would make it into a nice funky site, with a retro design.
As for content, it would depend on what you want from the site imo. You could go for a web 2.0 style one, where people post up games from the past, then other users can comment on them. this could be done in a forum style (better for dicussion, harder to start off), or as a myspce style blog thing.
or you could go for the straight up, info, history, pics etc style of site, with minimal user input. easier to maintain, but less fun imo.
