mebejoe povr has all the features that @Jacksonjdr94 is referring to. It is the reason I signed up with them and why I find myself using SLR less (along with their much more intuitive filtering).
This is an extremely under baked implementation of this feature and honestly, didn't even warrant an announcement.
All we have here is the ability to view a collection of videos saved by another user (that you need to know the url for to access). Not to mention that based on the examples given, it's likely one could yield the same or better result by just going to that category.
Without the ability to create a playlist containing snippets of videos (that play through as one continuous movie) and the ability to actually find these playlists, this 'feature' seems pretty pointless.
