I have been looking around for an app which allows me to blog on the go quickly and easily, I highly recommend BlogPress. It will save you a TON of frustration blogging on the go.
The BlogPress app allows you to post pictures, videos. It alsohas easy HTML integration. BlogPress support most of the mainstream blog platforms: - Blogger / BlogSpot - MSN Live Spaces - WordPress - Movable Type - TypePad - LiveJournal - Drupal - Joomla - Tumblr - Squarespace - My Opera
