wow, so many good answers!
regarding st33ds second post, i was thinking that the community site in question would deliver RSS feeds, which you then could use on your own site.. even comments.. could probably add a way to include commenting on your site, so it also appears on the community site.
reas: that's what i had in mind as well.. a flickr version for processing.. modified to fit the users needs.. flickr could be implemented, as the gallery-hosting site perhaps..
What still is a big question to answer is what everybody keeps saying about critical mass.. do we need to include the option to make a flash-portfolio instead, to reach critical mass?
The ideas i currently have to this project:
I'm playing with the idea to collect all the code (that is included in uploads) in "codes", "functions" and "classes".. so one could browse for a certain function, or class.. whichever you'd need..
The comments would also (unfortunately) include captchas..
A blog should also be implemented, so one could blog about projects, or regular stuff..
Private messaging.
Sketches are basically the portfolio.. each has a title, description, thumbnail(s), date uploaded, date modified
They can be also linked up to blog-articles.
And every user has a profile, where they can add picture(s) and info.. the blog is displayed here as well (i think)
Feel free to add to this.. at least the ideas will be available for everyone to see
