I saw a good amount of tweets mentioning the service at the SXSW. A lot of tweets weren't tweeted directly from go800 twitter account, which is good because that means. People are tweeting it on their own based off just interest. I usually go to the Twitter search option, and type in "goig" or "go800" an that brings up a timeline of what ppl are tweeting and when/how many. You can check those searches without having a twitter account.
