Make blog post private?

I wish blogspot will make available the feature of making a post private like how wordpress can.
It would make things easier for me if i ever decide to reveal my blog. At the moment only a few people know of my identity for this blog. Otherwise, i'm just another cyber "character". Anyway, i couldn't decide if i should start a new baby blog. Some things i would love to keep private but some others i would like to share. Well....hope blogspot come up with the feature soon. It definately will be useful!
