I'm glad to hear DHH is is in the news again: it reminded me that it was time to finally cancel my hey.com account.
I'd stopped using it a year or two ago, but it took a while for me to be sure all important email was going back to my previous email address.
It's a shame - there are some interesting UI ideas in Hey - but it's been clear for a while that I don't want to be associated with that guy every time I send an email.
