I have an app that I want to build a "recent activity"/firehose feed of 2-3 combined types of activity such as posts, comments, and likes of posts, and something else + maybe more later. I assume this is done with a query of taking the last of the appropriate object added to the DB and combining it with the last of the other type of object and ordering the new combined list of objects by their timestamps. What is the best way to do something like this? For now, I have something like this for every time someone refreshes the page:

```
NewPost.objects.all().order_by('-postdate')[0:10] #takes the last 16 recently added posts
Comment.objects.all().order_by('-commentdate')[0:10] #takes equal number of comments site wide ordered by timestamp

```

So what is the best way to take both of these querysets and render the different Models in 1 list ordered by their timestamp? I assume the type of logic will be the same for adding additional types of objects, so I just want to know how to do it with just 2. Thanks!
