The Lullabot Mailing List has different options. You can receive updates from Lullabot.com (such as this blog post) on a daily basis, a weekly basis, or not at all (announcements only).

This post was published the day before the event (admittedly a bit short notice). But if you didn't receive notice until Monday, you might want to switch your mailing list settings to receive daily updates.

You can switch your setting by clicking on the "update your profile" link at the bottom of any of the emails. This will bring you to a page where you can change your options.
