Here's a feature I think would be really great. I have suggested it on reddit, but maybe this is a more direct channel.
Let users submit tags for videos from right within the app (Deo/SLR). Make the tags automatically time-coded, and let other users downvote/upvote the tags so that incorrect tags are voted away (you will have to find a good cut-off point for when a tag is no longer shown). There should be two types of tags; 1) tags that apply to the video as a whole (such as MILF or Teen), and 2) tags that apply to that particular point in the video (such as deepthroat or prone.bone)
Have a limited number of tags available for use, so as not to create confusion. No reason to have both "large.tits" and "big.tits".
Maybe some sort of reward program for users whose tags get a lot of upvotes, to incentivise them to use the function.
