So I moved to Google Groups and then had feed problems:

* http://groups.google.com/group/whits/t/89a1526ca721bace
* http://groups.google.com/group/whits/t/7b9e1fe727f67975
* http://groups.google.com/group/whits/t/f899537e80031600

And even after I hilariously used one Google service to fix another, I
found that the post links were all messed up. But post links have
always been messed up, so I figured it wasn't that big of a deal.

ENTER THE NSLATINATOR. Not only did Noah not accept that this was not
that big of a deal, but he wrestled it by its serpent throat and gave
it the pummel treatment until it begged for submission. Yes folks, I
give you the one and only, amazing, Google Groups Yahoo! Pipe
Syndication Mashup!

You put in a Google Group name, and it gives you a nice feed out.

Of course there are still problems with the feed that it gives out.
You can't use your own title and description unless you clone it and
do boring things, and you can't change the feed URI either. But for
the title and description problem, you can at least use Feedburner.
Since I'm already using Feedburner, this was pretty easy:

Optimise -> Services -> Title/Description Burner

So there you have it. Yahoo! turns out to be better for fixing Google
services than other Google services. Though, I did still have to use
the Google Feedburner service to fix the Yahoo! service which fixes
the Google service. Call it a draw perhaps.
