I was mostly looking for information on how people would like to wiki-tize the OPs but it was made pretty clear from the posts that the idea of highlighting the best posts in large threads for expedient reading was much more desired so I've started working on that.
As a stage one for this extension, I'm running an automated process every hour to look through active threads and start paginating it into best ofs.
To make this more fair and to adjust for new site activity over time, each thread is broken up into n pages (currently 3) and the most positively reacted n posts from those pages are identified. Those posts are the ones with gold borders in recently active threads. Expect some wonkiness in the newest pages of a thread, as I've not done anything to (for instance) stop the first post on the 4th page of a thread from getting highlighted if it has no subsequent posts.
I'm doing this now so people can give feedback on how my idea works before I begin figuring out how I want to use this data useful. I am debating between adding a totally new threaded view of just the best posts, or adding a button that says "jump to next highlight" while keeping you in the real view of the thread. I am leaning towards the latter.
