Blogging Blank

What happens to a blog if you have nothing to write about?

Does it just disappear?

Does it take up valuable space?

Does it die a horrible death?

I've often thought about all the dead blogs out there in no mans land and what happens to them once people just give up on blogging.

Do they just sit there and gather dust?

There must literally be millions of posts, articles or just vacant blogs out there.

What is a good name for these blogs HMMMmmm

NOGS, BLERGS????

I just can't seem to get it out of my head that the space being taken up by these old blogs must be immense.

Is the space infinite or am I just being paranoid about something I needn't worry?

Why do I feel that I need these answers?
