Ah, nostalgia!
Yes, chronological blog feeds were hot back then, but now that FB/Instagram have taken over the role of lifestreaming platform, we're starting to see some blogs move away from the constraints of "chronostreaming", and more towards a collection of essays.
Search traffic also tends to have a power law distribution, so the majority of your incoming traffic will be focused on a few popular pages, meaning that in the long term there's really no need for an sequential stream of posts. One of the main benefits of a blog is its ability to earn search traffic for years, so why limit yourself by dating your own content?
