RSS for event invitations instead of an email list?

I have been thinking about getting rid of my email list for event invites that I’ve had since 1998. I’ve never promoted it all that aggressively and I don’t always send tidbits out to as often as I write about events here at I was thinking everyone on that list should just subscribe to my RSS feed since I usually write about my events here anyway. But the email list has about seven times more people on it than the number of people subscribed to my RSS feed.

How do you inspire people who don’t know anything about RSS to use it? Do you know anyone who has moved away from email announcement lists for events and is using RSS instead?
