Blogger updates the date in the article but not in the URL if you repost something you posted earlier.

Look at the URL. Blogspot allows you to retroactively change the date, but the URL stays the same. Obviously one might wonder why he changed the date.

It was first published in 2005 according to the URL and comment permalinks.

References all the way to 1998 can be found over the internet these days..

But can they be trusted? How much do google and archive.org control?

yes, and according to webarchive. strangely Nagy's post is gone in the archive, but present today. perhaps some quirk in blogger or webarchive.

This means Nagy didn't comment until after the archive date. He probably commented when it was re-posted in 2008.
