Official Blogger app arrives on Android
The Blogger app supports multiple accounts as well as offline mode. The latter allows you to draft a post even when you don't have any connection and share it online later. The app is nicely integrated through the Share option on Android, so you can blog pictures from your gallery without leaving the gallery app for example. If you have a Blogger account and an Android phone, it is pretty much a must have, so check it out on the market here.
