There have been sporadic reports that Google Reader does not display content sometimes. For me, this is chronic, but I haven’t isolated the cause yet. There is a work around that I haven’t seen discussed: the page displays properly with the sidebar expanded. When the page renders empty, there is not a lot of hint that it can be expanded.

I haven’t dug into Firebug to see why this is the case yet, but it should be fixable with a Stylish or Greasemonkey script, I’d imagine.
