The Time Machine.

Web-logs are like nothing else.
They have long interested me for a reason that is not very obvious.
At least, not until it is noticed:

They run backwards in time.

Like a Time Machine that is strictly one-way.
Visit what was, in real time.
Skip, delay, re-play, re-live the writer's life at that moment.
Unusual, that.

Easy to see, with a blog, where one has been.
Taken in context, with what is, might the future be predicted?
Probably.

Witnessing the collapse of their own civilization, some feel compelled to record it, adding their own unique insights, fears, opinions and prophecies.
Like a tenuous gas cloud, swirling, spiralling, sucking in whatever is nearby, coalescing into a vision that may - or may not - be real.

What you believe can become what is.
