http://m.xkcd.com/ will show the alt text right below the image. It's easier on my eyes.
I can't seem to get it to work in Google Reader. I get no mouseover text at all, neither the Comic Text version nor the default Chrome version. Am I doing something wrong?
Hmm... I see the same issue. Let me see if I can figure out what the problem is.
Aha! It was a z-index issue. I'm publishing the fix now.
Ok, the fix has been published in version 1.0.1. However, after you update you'll have to go into the options and "Reset to default CSS", then save, before it will work.
That's not a problem with Chrome, it's a problem with Windows. Tooltips on Chrome in Ubuntu last indefinitely until you move your cursor out of the element.
It's a problem under OS X as well
Funny sidenote: The Reeder app for iPad and iPhone implemented alt-text viewing because of the XKCD site.
A grateful nation thanks you.
You're quite welcome! I hope I've made everyone's day just a little bit easier.
