djh,

your question 'what are the odds?' cannot be answered for it is too unspecific. If you mean the odds that for a specified post, e.g. yours, another person is posting similar thoughts at the same time, the odds are very low. If you mean the odds for a posting of simultaneous posts with similar thoughts by any two persons within not too short a time, the odds are very high.

The point that is counterintuitive for many is that something with extremely low odds for happening at a specific time ot to a specific person has extremely high odds to happen at least once if given a lot of opportunities. So the odds that you'll roll three Sixes in succession when you want to is extremely low, the odds that this happens to some player if you are several persons playing a whole evening are very high.
