Perhaps you already know this, adding ?v=0 to the end of the URL to see the older version. I even drafted a quick Greasemonkey script for this, but it would need to run on all domains, as some of those blogs have their own domain name outside of blogspot.com
Thanks for the tip! I let myself get miffed at the "grow up" message and forgot one of the prime rules of the intertubes: there are probably smart people out there who have already solved your problem, you just have to remember to look for them.
