This is not a cool or self aware cover, this is lazy design.
Resting on the hashtag as a symbol of "digital is what took this thing down" is only kind of right. By employing a hashtag, Twitter's currency, as the central focus of the design, they're implying that Twitter was the Newsweek killer and its inevitable replacement.
This cover could have spoken volumes about media history or perhaps showcased the legacy of Newsweek, but instead, they chose to promote a hashtag that no one will want to use. Tina's last fumble, everybody.
