Almost all index pages are zero effort machine generated pages. I'm not entirely sure about it being an effect over time but Newspapers use to have tiny articles summarizing page 12 which later(?) became "more on page 12".

For a while (until I got to lazy) I maintained a front page article that talked about everything going on in the blog linking to tag pages that should have (but didn't) enjoy the same love. It was challenging to have a single sentence describe a group of articles and string those sentences into an article that sufficiently hides the truth that the blog randomly rambled all over the place. There was a lack of urgency for new articles to appear (except from the rss feed) in stead the front page article revealed missing posts. You could compare it to a wiki (while html offers the same utility) but the blog had 3 clear levels and blog like articles that rarely got updated.

It had me spend some thoughts on the absurdity of putting a log file on the front page or attempting to massage that automation into something nice? Everyone is doing it so it must be right.

It seems perfectly appropriate for machines to write 'Stock X goes down as Y happens' articles.

They have the same explanatory power as similar drivel written by humans, and you walk away feeling similarly uninformed.
