Don't you hate it when a link that someone (or yourself) posted is dead? Either you get an error 404, page not found or are redirected to some other page w/o the content?
Do your duty by taking some time to submit content to The Internet Wayback Machine aka archive.org! Just copy the URL, go to http://archive.org/web/web.php and paste the URL into the box underneath The Wayback Machine. You might have to click Latest a few times to get it to submit.
For instance, I noticed many of the toyota.com links at http://priuschat.com/threads/toyota-to- ... 568/page-4 are now dead. But somebody did submit them so that we can have the benefit of looking at their content later.
I added a bookmark to http://archive.org/web/web.php in Firefox's bookmark toolbar so it's pretty quick and easy for me to get there.
Unfortunately, if the site excludes robots via robots.txt file, the page won't get archived and there's not much you can do about it...
