Wow, I stand corrected. I must have been thinking "50% of twitter is not from the web" and translating that to "50% is from txt". Apologies.

I stand by the value of SMS as a driver of valuable content, and in the developing world.

Possibly, but since it only accounts for 3% of tweets, I think they could pretty safely change the limit if they felt like it.
