I hope you mean "wasted" in a good sense, otherwise I feel depressed for spending a ton of time on here :) Anyway, here is my list, in no particular order:

1. The unique approach to gamifying the social aggregation concept so that "internet points" actually mean something and play an active role in helping to bring the helpful and creative members of this community to the top which promotes decent interaction and fights trolling and spam without sacrificing free speech / freedom of expression
2. It looks and feels different from other aggregators & social sites which is pleasant and refreshing (even addictive)
3. It focuses on the individual user giving them the tools to create a meaningful profile that others can follow and interact with giving a user the feeling of self even though they have the benefit of remaining anonymous
4. It has a lot of great features that bring the best from a number of social platforms under one roof (I made a list a while back, its a little out of date but many still apply)

The one thing that would be great to see is the community growing larger over time so that discussions are a more prominent sight in my feed and the vast tribes we can visit and contribute to.

The content posted and generous community mostly.

The content and the communities effort to give credit to the snaps they post. Social media striving to be the elite!

I like the variety of content that people provide. And that there is literally no spam so I don't feel like I'm stepping around any land mines.
