I've noticed the disappearance of those sidebar links as well. It takes more time to go to forums and find and click on the most recent post link to accomplish the same thing.

A couple of notes on observations on the "mini-page" issue I am having.

It looks like these mini-pages are your mobile site. Looking at your homepage on my iPhone, the layout is identical, with all breaks the same. The actual content displayed, however, varies.

The second observation is that they show up when I'm running Windows just like they do on the Mac. This leaves the real mystery as to why I see them but others don't.

Just viewed the Preview and I do not see another set of the mini-pages.

OK, I've restored the side bar and disabled the prior caching mechanism I was experimenting with.  I had to remove the forum postings since that was dynamic content.  Hopefully things are better now.

Bryon - the "mobile" site is what is called "responsive".  You can simulate it by shrinking your browser window.  I'm not sure why you seem to be the only one having those issues.  I will continue to look at it, though.
