I'm pretty sure you'll not get user preferences in the nodelets for quite a while (if ever). Nodelets are rendered on every page load and so are best when they can be cached. And cached nodelets can't be user-specific.
Yep. When i wrote that reply I hadn't realized the implications of the node caching on what I was saying. In fact I _keep_ forgetting them.
Your caching for best/worst nodes is quite nice but it still reads quite a few records out of the database. Doing that 4 times for every page load would probably end up with more DB load than we had before your work.
I agree totally. Would it be too much (in terms of policy etc) to make small versions of the various nodelets? With say 5 lines in each, and a link to their respective full page version?
First they ignore you, then they laugh at you, then they fight you, then you win.
