1298.

The article doesn't answer how many, so I've counted.

It takes 1298 GNU/Linux users to change a light bulb.

Including the father of the first user, excluding the 6 that complained, and then complained again (they're counted only once). And also, assuming there's no overlap between all the groups, which is probably unrealistic.

So it takes 1299 then, if we include you.

1301, to be more precise.
