Well, on the one hand... just because someone else gets a GLBT network on the air before TTN doesn't necessarily mean that TTN won't surpass it... after all, Internet Explorer came on the market after Netscape, and we all know which one is more popular.
On the other hand, TTN has to actually GET something on the air -- and it has to be of sufficient quality to attract subscribers. From what we've seen so far, it looks like they're more interested in selling their own stock than they are in getting their network up and running.
