According to my dashboard thing Blogger now has a featured post widget you can add to your blog:
"As bloggers, we all know how important it is to post frequently in order to encourage readers to come back. Of course, the more you post, the more quickly your posts slip down into the archives, making it harder for your readers to discover everything you’ve posted that they might be interested in.
To help make it easier to showcase the posts you want your readers to see, we’ve created a new gadget called Featured Post. With Featured Post, you can choose posts you’ve shared on your blog and highlight them wherever you’d like."
With eleven years of almost daily posts I think I'd probably spend the rest of my days digging through the archives to find everything I'd like visitors to read, and I'm not crazy about tweaking the sidebar every week for new stuff, so I won't be using it. But if you don't have to deal with a lot of content on your blog, this might come in handy (especially if you're an author on Blogger promoting a new release or holding a giveaway.)
