Imagine

Think of how much stuff is "out there" in magical internet land that is just wasting space.
And I don't mean dull people's facebook or twitter pages, but legit space-wasters, like this blog for instance, that has been sitting here untouched and un-looked at for over a year now. And thats only a year.
I wonder if they will ever spring clean the internet, so to speak. There would be a shit-load of stuff to get rid of, thats for sure.

Perhaps there is an analogy between wasted internet and space junk?
Its not so important now, who actually goes into space these days? A couple guys a year, thats about it. Maybe more now that the Chinese are venturing that far. But when the time comes that you're wanting, well, space in space, there might be some issues. Maybe a time will come one day when internet space is a premium...

But then this is the internet and magical and they can invent more space from nothing.

Build cities on swamps.
