How about... we do both? Because it's not exactly too much effort to set up an atom and rss feed to go along with your email newsletter.

Can we stop (subtly in this case, not so subtly in others) crusading against tech that we don't personally like, when thousands upon thousands rely on it because that's the format they're comfortable with and want to receive periodicals in?

Set up a system that meets people where they are instead of forcing them into only your preferred delivery flavour.
