[Django + Python] Smarter Events filtering

[judtinzhang]

Since we have a wide variety of events being collected, we need to find a way to make this more personal to the user. Otherwise, a billion irrelevant events will show up on their feed, and because of that they stop using the feature.

Possible suggestions could include the ability to swipe-delete an event from their main feed, some form of aggregating events, etc.
