RFC 6068: The 'mailto' URI is suppose to use commas to separate email addresses.

Outlook: Fuck you and your specification I want semicolons unless the user's regional settings has a comma specified as a list seperator.

So I just heard a person giving career advice say not to use mailto on your profile as a button. The reason is that, "she doesn't use the apple email thing, and it's annoying having to copy and paste it into Gmail. At which point, her attention is lost." do these people really make any decisions at any levels at all? God help us. (For the record, I don't believe in God).
