Moblogging sprouts

There has been a number of new moblogging start-ups appearing in the US and Europe. In the US, I have noticed Textamerica and Buzznet. In Europe, there's Ploggle and MoblogUK. My friend Alan at Phlog.net has already got a very large number (100's of 000's) of active subscribers. Could this be the new killer mobile application? possibly - although I think the services need to be even simpler to entice the mass-market. I suspect current growth is satisfied through "early-adopters", and that securing larger audiences will need simpler submission mechanisms, such as device apps that auto-send pictures/video to the blog and/or sending pictures to a MSISDN.
