I personally don't think that web email is targeted at teens. And since it's mentioned web email - does this mean email apps in smartphones and corporate email aren't included? I just love how the media is always trying to say something is dead based on some simple stats. Good times. Just like how everyone keeps mentioning the death of the web, death of Microsoft, death of Apple, death of Google...
Exactly this. My web based usage of e-mail is down -- simply because I usually get my e-mail on my mobile phone. If anything, though, ease of access through mobile devices has increased my total usage of e-mail.
