This idea came out of a discussion from a question asked by Noah Brosch of Tel Aviv U. Henry Leckenby also made significant comments. I believe the whole discussion was indeed prompted by the articles that are at the base of this discussion: http://bb.nightskylive.net/asterisk/vie ... =8&t=17591
titled "Why large hadron collider can never be activated?" Background on this is the NY Times article about how some physicists proposed that future people might be sabotaging Europe's Large Hadron Collider. See: http://www.nytimes.com/2009/10/13/scien ... 13lhc.html
Anyway, this idea centers on one way that people from the future might be found here in the present: by the possible existence of "pre-knowledge", knowledge that doesn't yet exist but will soon be created. For example, knowledge of the 9/11 disaster didn't yet exist in the year 2000, so if your neighbor kept asking you all through 2000 if the twin towers had fallen yet, they might be from the future. Or not.
The discussion eventually led to the APOD log files. So, just for laughs, I started the project by checking one of the APOD log files for any search starting with the word "Comet". There were a few entries, but no one was looking for a comet that I did not recognize. If, for example, there was a search for "Comet ABC" -- and Comet ABC is discovered only the next week -- that would be interesting. One might conclude that, on that day at least, no future people forgot their time coordinates and mistakenly checked APOD for a comet they should not have.
Here are some answers to your questions. Yes, I am feeling OK. No, I am not ignoring any prescription medication. No, I do not seriously expect to find people from the future this way or any way. Yes, I consider this mostly entertainment. Yes, I would be interested in your thoughts.
More generally, is there any utility in searching out "pre-knowledge?" I note that time travel is almost as popular as space travel in fictional books and movies, so things like this certainly capture the public's interest. Yet, I can think of few research efforts in this direction. Are there any other ways of ferreting out pre-knowledge?" Should a broader search in APOD's log files for pre-knowledge be done? Should a contact be made to Google or someone with access to a the search inquiry database of a major search engine be made?
