I put up a post that was full of some half baked ideas and theories. The post was up overnight and then I took it down. But the web crawlers or whatever you call it that scrape and mine data from a website that then stores it in some cache that leaves it on the Internet forever had already done its thing. I deleted the text of the post and replaced it with a single sentence. If you searched for any text from the original post the Google search engine would find the post but when you clicked on it to open it, it was the sentence post and not the original post. It was an experiment to do it that way and appeared to have worked.
But then the post's suggestive title drew comments anyway with some interesting but incorrect guesses as to the reasons behind the removal. To complete the experiment, I took the replacement sentence post down the next day by "unpublishing" the post. So, is the original or replacement post still cached on the internet forever? You tell me. Can you find a copy of the original or replacement post on the Internet anywhere?
