Something I have realized...
When you jump through the hoops and do the workaround to create a "sticky" post in Blogger, now that post-dating makes a scheduled post, said post never shows up in the feed. So, if you create a post that you think is important enough to stick at the top of your blog for a period of time, your readers who use some sort of feed reader will not see it.
Brilliant, Blogger, brilliant.
I noticed this because I keep missing Cowboy Blob's weekly caption contest.
Blogger really needs to create real "sticky" functionality now that they've changed the original function of post-dating.
UPDATE: Just checked Blogger Help, and this isn't the only problem they're having with scheduled posts.
