Google and hidden divs

It appears that Google has thanked me for my fancy blog system at our site (click signature) that takes advantage of a div that can be hidden and opened with a click without reloading the page.

I realize people may be using hidden divs for spam, but there should be a way to legitimately use these without getting penalized. Dammit, all pages with the blog bar got wiped out of Google altogether!

How annoying that legitimate use of technology is thwarted by something like this!

A good morning's rant, that is.

And I find that another website has gone way down in the ranking due to a simple hidden div opened by clicking an envelope figure, saying "Click this to send to a friend", which then opens a form for sending to a friend! How annoying is that!

And here's the rant that was sent to the Google support.

This issue also came up in another recent thread. I am cross posting (have mercy), as this is the search engine area and people concerned over this would do well to find it here, as well.

I have posted a thread at Google Groups / Google Problems concerning this. Drop in and post your comments. (Direct URL.)
