For a while now we've seen that images in our Pika atom feeds were not displaying in some feed readers. In fact, they weren't displaying in my own feed reader, which routes through Feedly. I was sad. I spent a lot of time troubleshooting this. Compared our feed with a lot of atom and RSS feeds that worked. Eventually I came to a hair-brained idea: what if Rails's Action Text image display markup was confusing these feed readers?
