Nov. 17th, 2009 12:36 pmThe Wikipedia Paradox:
To determine whether any given subject deserves an entry, Wikipedia uses the criterion of notability. This lead to an interesting question:
Question 1: What’s the most notable subject that’s not notable enough for inclusion in Wikipedia?
Let’s assume for now that this question has an answer (“The Answer”), and call the corresponding subject X. Now, we have a second question whose answer is not at all obvious.
Question 2: Is subject X notable merely by being The Answer?

Date: 2009-11-17 09:41 pm (UTC)To see why this is a dangerous assumption: what is the largest number that's still smaller than 1?

Date: 2009-11-17 09:44 pm (UTC)Second: There are an infinite number of numbers smaller than one. The set of things that are notable but not notable enough for Wikipedia is, by necessity, countable. Making the assumption fairly reasonable, all told.
The original post goes into more detail on this.

Date: 2009-11-17 09:48 pm (UTC)I wouldn't consider that 'explicit'. You asked "what's the most notable subject", which implies that there is a well-defined most-notable one... but I've seen plenty of people make assumptions of that nature without realising that this is, in fact, an assumption that isn't automatically true.
The set of things that are notable but not notable enough for Wikipedia is, by necessity, countable.
I take it you're using 'countable' to mean 'finite' here, rather than in the mathematical sense - in mathematical parlance, the set of rational numbers is 'countable', but there's still no "greatest rational number less than one".Now I check the post - he is using 'countable' in the mathematical sense, and his argument is not correct.

Date: 2009-11-17 09:47 pm (UTC)If the standard for inclusion is notability, there must be a line between "sufficiently notable" and "insufficiently notable".
