The singularity at the Schwarzschild radius is removable. With a different choice of coordinates, you can get rid of it.
The time it takes for the horizon to form depends on the reference frame of the observer. For some observers (someone watching from afar), this time is infinite, but for others (e.g. an object plunging into the black-hole-to-be) it is finite. Anyway, this has been the traditional view; the article says otherwise.
