When Blogger in Draft (actually just a name for an experimental Blogger account where new features for Bloggers are introduced and tested), it just introduced 2 features - Autosave (Rat called this Auto####) and video upload direct from your Blogger post editor. They later introduced Polls and Enclosure links. As at time of publishing, Polls are still having problems and Enclosure links which allow you to turning your blog into a podcast easy.
There is some controversy over Autosave (including 2 bloggers who complained that they like to play with editing of their old post and if they don't like it, they just don't publish. Now with Autosave, their old post get overwritten without their "permission". I also complained that while doing edition of old post, before I finish with the editing, the untidy, unfinished post get published. I have to add the phrase "under editing" at the top of the post to warn readers). I have been pestering Blogger to give bloggers an option to turn off Autosave in such circumstances, but for unknown reasons, this very reasonable request was turned down.
Now Video Upload is out of beta (Blogger in Draft) and I am wondering if anyone will discover any similar problems. Now when you get into your Blogger post editor, you will see an extra video upload icon in addition to the other standard icons.
I will probably test it at Testing Blogger Beta (now New Blogger)
