First, I hope this festive season is great for fellow bloggers, readers, and everyone else. Merry Christmas!
Next, I came across two sites that I'm keeping an eye on and thought I'd mention here: Red Gate bloggers (makers of the excellent SQL Compare), and site called TracksLife that offers a free service to track anything as "lists" - TracksLife will send you reminders to update your lists on a schedule of your choosing, as well as making your lists (shopping lists, budget, diet, etc.) available via RSS if you choose. And of interest to me, the site uses AJAX technologies too.
