I've noticed that Blogger has implemented a couple of new features - one I have implemented and one that I have discovered accidentally.
I have turned on comment moderation for posts older than 14 days. For a while now, I have been getting - I guess - manual spam postings on really old posts. It's somewhat annoying as I sometimes head straight to the blog instead of the offending post - then I got to search for it or root back in my email. I'll keep it to 14 days.
Blogger blogs can also future schedule postings and they won't be posted till the day of. This is the one I found accidentally. If you time your post time to be a little off from Google servers, it thinks it's future dated.
