Even just a simple tagging system would suffice. One to two tags attached to the submitted link would be great. One could use Reddit for this, but I prefer the average comment/article on Hacker News to the average comment/article on Reddit. (:
I agree. While I like Reddit, I think they've missed a trick by not just using tags. It'd much rather see all posts in the Reddit ecosystem tagged "Ruby" than just those that were directly submitted to the Ruby subreddit, for example. That's a bit like Delicious, though, I guess.. just with commenting ;-)
I guess the only problem there is that it makes it harder for one community focused on a certain topic to "branch" to another when things get rough, whereas now you can just start "/r/ruby_two" or whatever if /r/ruby makes you mad. It's definitely a trade-off, but I think Hacker News is still high-quality enough that tagging would work.
