Hot post sorting

Not only with Diaspora, but also with other social networks, as your contact list grows also the number of received posts is growing. Usually, as is the case for Diaspora, posts get sorted chronologically and reading all incoming posts becomes cumbersome since new posts are added to the message stream every few seconds.

So why not have some reddit-like "hot-post" sorting in addition to usual chronological sorting to give users the ability to handle their fast growing message streams?
