I agree. FE technologies are in and out of fashion faster than anything else, it seems. Dig in and hate away and then maybe your knowledge will get a slightly longer ROI.
The UI could still use polishing. For example, the attachment confirmation dialog is so confusing. I'm tempted to send them a patch that makes the wording clearer.
"Did you forget to add an attachment?" ("Oh, I didn't!", "No, I did!")
The bullshit didn't even have to be believable: "Marilyn Manson was the kid that played Paul from the Wonder Years. Also, he had a rib removed so he could perform autofellatio." Kids everywhere believed that. Hilarious.
