In the good ol' United States of America, the receiver pays the SMS bill. In Canada, Australia, Europe and I believe much of Asia, the sender pays. For Twitter, this may add up fast.
If you spend some time on Twitervision it's obvious that Twitter is a global phenomenon. The site is popular around the world. Further, use mushroomed in the last few weeks.
So unless I am missing something, Twitter faces a massive SMS bill for all of the messages it has been sending out to users outside the US. Perhaps I am wrong. Maybe because they are US based our rules apply. If you're an expert in this area, please weigh in.
Further, from the looks of it no part of the site is monetized right now. So add this all up and it could mean big trouble in Twitterville. Please do correct me if I have this wrong.
