Q but No A

Not many answers tonight, only questions and more questions.

What's really the difference between a line and a horizon? Is the actual trick here that, by definition, you can never reach the horizon, that no matter where we are, the horizon stays the same distant away at all times?

I've spent a couple of summers in Central Texas and I know that this isn't something that one does by choice, so why is Netroots Nation, essentially a convention of progressive bloggers (formerly Yearly Kos), holding it this year's meeting in Austin in July?
