maybe. But forum seems like a cluttered way to post related links, it's better to have one discussion/thread per article if in forum form. And this board isn't so much about article/paper discussion. Thats why the newsletter is so great, it's like great compliment to the content on the board. And one thread per newsletter, might also be awkward, if yuo want to see/post stuff related to one link in the letter.

There is a really cool news aggregator called cor.ax (it origins from the swedish bubb.la). They operate like this: volunteers are posting interesting links on a closed "forum", then the members vote for which links to publish and what title they want to give the link. They focus on current events. But it would be cool to do something similar but only unix related and skip the time limit (they never post anything more then a week old i think).

Maybe I went a bit OT, but it's a bit related. But a wiki or some kind of collective aggregator link archive would be something.
