I read that three times and don't think I got anything out of it. So did he make any money off of it, or not?

I too am in the same boat. I am not sure where the author was going with that, and yes, its a little hard to read.

Is it just me or is the text too light for the white background? I read the article by highlighting it.

It's not just you, light blue on white is a bad combination for body text.

There is a reason that nearly every book ever sold used black text on white background even in the 20th century when that was no longer the only choice. I only wish that websites would heed this advice more often.

Those pages were not the equivalent to staring into a LED light. :)
