Blogger is running a beta on the Dashboard, and they've added something I've wanted for a long time - the ability to publish post-dated posts. This is a test post of that very feature.
The only thing I definitely don't like is that the HTML Editor has no buttons or keyboard shortcuts. Hope they fix it. Another issue is that even though you can select the beta dashboard as your default, if you choose to edit posts from your blog, it still takes you back to the old version. Oh, well. Can't have everything.
Anyway, if you're on Blogger, and have been waiting for the functionality that the rest of the blogging world has had for years, give the Dashboard Beta a try.
