Note that if there is a lot of text traffic on a given number, carriers like AT&T, Verizon, et al will block texts to and from that number until the traffic subsides. What's worse is that if you send a message to that number from the Twilio dashboard, its status will be "sent," but you will not actually receive it. Apparently in the world of SMS, "sent" simply means the message has been delivered to the destination carrier, and it is not a delivery receipt like with iMessage or BBM.
Twilio suggests that, to reduce this risk, you load balance across a collection of such numbers, or purchase a short code, which isn't cheap: http://www.twilio.com/sms/shortcodes
DOTGO solves the problem of service discoverability by mapping domain names to shortcodes representing TLDs. Want wikipedia.org? Text "wikipedia" to DOTORG (368674). Want to checkin to Foursquare? Text "foursquare" to DOTCOM (368266).
DOTGO also provides a language of reusable components, known as CMRL (Concise Message Routing Language), it allows you to create hierarchical menus, links and URL callbacks.
They're available in the United States and select countries in Latin America, Africa and Asia.
Previously, I was a web application developer for them, I still think it's a great idea and recommend you guys give it a go.

Beware though, if you txt a lot, you won't like it. Not enough real estate for the crazy font they use.
There are also these printed cell phones showing up. Do a google for "card phone". Pretty interesting.
You can still find some of them on eBay. I'd offer mine, but I'm keeping it as an emergency (911) phone for my car.
Eventually I traded it in for a cheap nokia with an lcd.
I'm sure it has some additional bling like FM radio, a media player or whatever and some games, but I use literally use that phone for nothing other than calling and texting.
I ended up breaking the chain and switching back to an iPhone 5 but this app store has got me pining for the simpler days of pure sms and voice based comms.
"if this becomes popular"
is a nice problem to have, in general
I'm in the UK but this is a far bigger problem in other countries so if executed better this would be very interesting.
I didn't feel like typing too much :) What service does it use?
