Hello Ben,

I found one blog post that has a weird text shows up on top, see the highlight text in following image:

The post is here: http://www.benorenstein.com/blog/a-handy-ruby-trick-class-new/

I think your blog post
"How much should global variables cost?"
is great except for one thing:
the body of the post never actually mentions the "global variables" mentioned in the title.

I bet I'm not the only person wondering if maybe something got accidentally chopped off and lost in the series of tubes and processors between your brain and my eyeballs.
Maybe the you deliberately left out "global variables" for some reason that maybe to you is obvious, but the implication you alluded to is not so obvious to those of us who cannot telepathically read your mind.

Perhaps you could duplicate the "Use of local variables" section, creating a "Use of global variables" section with a (much higher) fee and a pithy summary.

Or perhaps it would be better to explicitly state at the bottom of the post something like
"I deliberately did not specify a fee for global variables, because rather than try to eliminate global variables at all costs, I want to remind you to think about all the other things you could do to make your code more awesome."
