I would also suggest the application of default tags, such as "n00b" when the article is posted by someone with less than (total_age_of_hn / 5), "anonymous" (with strong flag bias) when the account is less than a day old, "oldie" when it's a dupe that was reposted.
I'd like to be able to ignore gadget porn (here's this new iPad cover!) by default, and weigh the programming/science/DIY hacking/design topics higher.
That's indeed a potential issue, same for filtering. I'm not sure how much caching is going on, but it'd make any caching in place much less effective. Maybe only give that option above a certain karma.

Anyone would suggest more?
