I guess it would be logical to expect it but it does not seem to affect the rankings anyway. The last update on the page that actually ranks is older than the same question was posted on my site and so by definition, each of the 11 or 12 updates my page has had since then is more recent. Yet the other page comes up on search and not mine.
does a document that gets updated assume a more recent stamp?
These two pages are not yet a month old. I wonder if Google will eventually re-evaluate them on the basis of their content and not "who posted first". I don't know if it's actually the case but it would make sense if "posted first" would only matter for the first couple weeks or so. After which the news (if it were a news piece) would have percolated down the system and some detailed commentaries would emerge that are worth listing in their own right. Once again, my example is not a news piece but perhaps the same approach also applies to other types of content?
