I plan to implement votes (maybe), domain, actual raw text of the article, title, submitter (maybe) and show articles that are deemed "important" (i.e. have stayed on the front page for longer than X hours), as well as some random ones, to avoid a bubble. Plus, I've already started training the filter manually, I'll maybe write a simple web UI later on so I can up/downvote articles from there.

I think that should give a good first draft.
