I think that showed up after I tried to click Like on the post, by the way.

Never seen that before. Is it an active button, or just text?

The button is no longer clickable. The letters can’t be interacted with at all.

Interesting. I just came across that this morning. I don’t know. In Java it means stack overflow, which is a memory problem.

I suspect it’s some sort of bug one way or another.

NaN is computer speak for “not a number.” It’s a kind of fudge, technically it’s a number, but it is the result of operations such as “3+2+’hello world'”. That is, instead of throwing an error when you try to add a character string to a number, Java and many other programming languages generate this not-number number. The advantage of this is minor errors in operations do not always the entire system to fall over. The disadvantage is that typos in coding can easily slip through precisely because no formal error is thrown. Someone has amended the script counting likes, and probably accidentally put a letter in there. I’m sure once its noticed Facebook will correct.

NaN means “Not a Number” it is an error databases through when there is either no data, or a formula built into the software has literally tried to divide by zero. And usually the reason it is trying to divide by zero is because some poller isn’t reporting any information. So “NaN” means there is some error in the data stream the software is using to produce or calculate some statistic.
