There’s an interesting conversation going on between David Xue, the founder of PixPulse and Roland Tanglao about the pros and cons of using email as a method to share mobile content.
I have to agree with Roland that email sucks for the job. I used email to upload to Flickr for ages until ShoZu came along. Shozu uses replication technology that creates a sort of background persistent connection it removes the requirement to have reception which of course is required for email to work.
