The problem with this idea is that:

1. We have posts on lots of different subjects, having a 'sticky' node on each subject would just be too many nodes at the top of each section, even if you could view them just as subject lines without the actual node being shown.

2. Someone/group would have to spend time selecting, adding, removing and generally keeping order of the sticky nodes, who?

3. And by far the most relevant, what makes you think people that dont bother to look through newest nodes, the frontpage or search, for something relevant to their topic, is going to take time to scan through sticky nodes?
