Being the only coder at my startup, you have to do everything. And the other day, I had to spend the whole day troubleshooting rendering differences between Outlook and GMail. It reminds me of the old days, back around the time of IE6, when it was all-but-impossible to get FF and IE to render the same HTML - except worse, by at least an order of magnitude. It's astounding to me that the same companies who've worked their asses off to make sure that their browsers all render HTML and CSS exactly the same, haven't given the slightest thought to making sure that their email clients can get along. This is a huge time-suck for developers. Glad to see that they're getting the public shaming they deserve.
