Normalise a post's weighting by its community's

When sorting the feed by "Active", "Hot" or "Top Day" etc, your "Subscribed" feed will tend to show posts only for the most active communities, while posts from smaller communities will never have as much activity or as many upvotes.

It might be nice to counter this tendency by comparing a post's upvotes/score by the average of the community it comes from, so that being "Top" is really "Top for its community".

You probably wouldn't want this to be the default. Perhaps an additional feed sorting option.
