Simplicity would be having tags to categories the posts.
Just like a library has the Dewey Decimal Classification system -- if it were not for that it would be just a chaotic heap of books.
What if someone missed 3 months worth of posts and they want to catch up quickly... is that still a "small set of posts easy to scroll through"?

You are saying it shouldn't be implemented are you not?
