I'm enjoying the Groove posts too, and agree with your general point - being upbeat is valuable, as is soliciting feedback and calls to action. I just think I'm too cynical to be too pushy in an email, even if it's dressed up as good-buddy niceties.<p>I mean, that '1 hour early' incentive is original and all, but it's clearly a confidence trick. It's a little insulting to his readers' intelligence, no?<p>Overall I'd say it was the content of the post more than the email copy that has made this series of theirs a success.
