OK.  Time for a funny bug story.

Yesterday I upgraded the running version of FlexWiki at flexwiki.com to the newest bits from my development environment.  It's the first time that the whole FlexWiki UI is built using WikiTalk.  I'll be posting information more information about WikiTalk and the new WikiBorders feature over the next day or two.  But anyway...

One of the UI changes is that the list of old versions of a topic are no longer listed in a drop-down with a button to show one.  Now they're links on the page.  Which means that web spiders follow them.  Further, on each historical version of the page is (er, was :-)) a link that will restore the historical version and make it the latest again.  Being links, of course, means that -- you guessed it -- web spiders will follow them. 

All of this was compounded by an older bug that prevented the NOINDEX, NOFOLLOW instructions for spiders to be correctly emitted.

So...

This morning we awoke to find that lots of pages on flexwiki.com had been rolled back to previous versions.  Wiki vandalism?  Proof that people hate us? 

Nope.  Just google doing its job.

Anyway, it's should be fixed in the next few minutes...
