You play this game by sending me a private message containing a real number greater than zero.
The winner is the person (or persons) whose number is the median value of all such numbers that I receive.
Please, DO NOT POST ANSWERS in this thread or anywhere public.
Rules and clarifications:

The winning entry is the statistical median (not the average) value of all valid entries. That means I will sort the entries by value and choose the one in the middle as the winning value. All entries equivalent to that value are winners. If there ends up being an even number of entries, the median is the average of the two middle values, in which case both are winning values.

Valid entries are any real, computable numbers greater than zero, with no maximum. You are not restricted to the integers. Fractions, decimals, and even formulas are okay as long as I can tell what your number is and easily sort it among the entries.

Please do not collaborate with others on your guess, as that would be a major advantage. Do not discuss your entry or this game with others until I have announced a winner.

One entry per person, please.

The game will end at my discretion. I want to try to get at least 100 entries, but if interest dies down sooner, I will just end it. On the other hand, as long as entries are steadily flowing in, the game could continue.

I will publish all valid answers on this thread when the game is over. The winner will be declared the smartest person alive.

Again, please DO NOT POST ANSWERS ON THIS THREAD.
If it’s okay with the moderators, I would like you to bump this thread with whatever (but not your answer) at the time that you enter. Also please use this thread for questions about the rules.
Think carefully about your answer, because we can only play this once! (Then the answer will be known!) If the game is a success, I know a couple of twists for future contests.
Good luck!
