Something strange is going on here

Last night I wrote and posted a long critical piece on Sunday's Hong Kong by-elections, entitled "Giving Democracy a Bad Name". This morning it showed up in my Bloglines. Noticing a typo, I opened up Blogger to correct it, only to find that the post in question had disappeared from my blog. I didn't delete it, so what is going on here? I don't want to start succumbing to conspiracy theories - it could be a software bug in Bloglines - but it does seem odd. Unfortunately I didn't keep a copy. Does anyone have any idea how I can retrieve it?

Curiouser and curiouser - a Google search shows up the missing post: http://ourprivatebeach.blogspot.com/2010/04/giving-democracy-bad-name.html - but when I go to the blog's home page, it doesn't appear, although this later post does. I suspect a bug in Blogger. I'll come back later and see if it's sorted out.

(Several hours later)
OK, sorted - I found the missing post lurking under the date 10 April instead of 17 May. Since I never even open the options window to set the date of posts, I still suspect a Blogger bug, but at least I can rule out more sinister explanations. I've amended the date of the post and deleted my repost of earlier today.
