After many years of using mutt in a terminal (which followed several years of using elm in a terminal), I'm switching to GMail. I like it already.
As an aside, since I've installed Movable Type and made blogging so much more easier than earlier, I've already blogged more in the last week than I'd blogged in the last year.
Unfortunately for you Lispers, none of it has been Lisp-related. Be patient. I'll get back to that eventually.
