Web 2.0 Mash Up Required - Blog Authoring

I was just writing an a post for the CIO weblog and was doing it via the web interface, its a movable type (Six Apart) Application. Well half way thru the post i was wondering if i should take an offline back up of the article just in case ....than i thought wont it be really cool if i could use GMAIL to author my blogs....with its Autosave feature..i wouldnt have to worry about this at all. Need to evaluate if there are better alternatives!
