There have been a couple of other really interesting posts on this topic from <ahref="https://www.swyx.io">Shawn 'swyx' Wang</a> recently.
In <ahref="https://www.swyx.io/smart-indexes/">this post</a>, Sean talks about the fact that index pages seem kind of backwards and echoes your point: does it make sense to have index pages as reverse-chronologically sorted lists of posts when maybe your newest post isn't that interesting (as he says "people report writers block with blogs, particularly after a big successful post, because it’s almost impossible to consistently pump out bangers").
In <ahref="https://www.swyx.io/sharding-yourself">this slightly earlier post</a> he talks about how you can "shard yourself" to make it easier to overcome writers' block - particularly for writers who blog about different interests. However, I also think this helps your visitors find relevant content more easily. I really like the example of <ahref="https://jvns.ca/">Julia Evans</a> who breaks down her content by category on the front page so it is really simple to find stuff you're interested in. I also really like
<ahref="https://shkspr.mobi">Terence Eden's blog</a> - he has links to each month going back to 1987 so you can explore older content if you wish.
