The idea behind the suggested score for interestingness is that this metric could be used to easily rank / order hits, probably in combination with a time-based filter (e.g. most interesting hits in the last 7 days, best ones first). Ideally this ranking would also replace / subsume the current moderation system, which divides hits only into interesting and not interesting.
Maybe the score could also be calculated for each (logged in) user on the fly (e.g. ranking hits involving the users home country / city / himself more interesting), but maybe not.
The goal of this ranking system should be ultimately to give EBT users a handy tool to see the really cool hits on a glimpse. Personally I'm also not very content with the current listing, I usually lack the time to browse through page after page of todays hits. This has been much easier 2, 3 years ago
Keep the ideas coming. Let's improve EBT together.
