One thing that is throwing us off a bit is that you don't use the link rel="alternate" syntax for your feed in the head, so we don't find the RSS feed. I'm seeing what else is going awry too.
 

Thanks for looking into this, Technoratians!

I've added...

<link rel="alternate" type="application/rss+xml" href="http://gojomo.blogspot.com/rss/gojomo.xml" title="Gojomo Blog RSS Feed" />

...to my template's HEAD. I'm just mimicking what I've seen used elsewhere, because a quick search didn't find any authoritative spec for using rel="alternate" to clue in feed-crawlers.
 

Looks like that did the trick - you're showing up in the optimism tag now among others.
(See, we love you really).
