OK, it seems like an interesting concept, but I'm totally lost. Maybe my thoughts will be helpful. Is it an iPhone-only thing? (It looks like an iPhone thing, but there's no app store link.) Is it a service which uses iPhone text messaging for its user interface? A smart phone thing, or a cell phone thing? I've clicked around every page here (short of actually registering) and I can't tell if I'm even technically able to use this. Is it just for people I work with, or for people I know, or will it be hooking me up with strangers? Will it always be the same group? The "How it works" page is pretty sparse: it looks like just a feature list, not an explanation. I was expecting something that takes me from "step 1, I'm sitting at home in front of my computer looking at damnsimplecarpooling.com" to "step 10, somebody is dropping me off at work". (All I'm getting from the screenshots is that I have to buy an iPhone and type "y-e-s" a lot.) I guess I could probably figure some of this out if I actually register, but I'm not giving away my phone number to an unknown service just to find out what it does. Promoting something as "damn simple" works great if it's something that's generally known to be complex, but carpooling is already pretty simple. I can just send email to everybody I work with (or post a message on Facebook) that says "Who wants to carpool from X to Y every morning at 7:20?". You should paint a picture for the potential user: how's this going to help me?
