I write a newsletter. I like that word better than blog. Blog implies a high volume stream of self-important writing. Instead, my subscribers get a monthly missive with a new recipe, musings on food or restaurants, and news of upcoming classes. I won't fill up your in-box, and I certainly won't ever share your email address with anyone else.
I use Google Groups to distribute the newsletter. It is very easy to Subscribe by email. The more state-of-the-art folks out there can choose to use their favorite RSS reader and subscribe to the feed. If you're worried you've missed anything, you can also browse past newsletters.
