I'm pretty sure that was intentional (or, at least, part of the joke), since there's this text right above it:

    Also you can get your own infograph done for about $150 bucks from
    "derri_hasmi at yahoo.co.id", although proof reading the infograph before
    you publish is recommended.

I will never understand how someone can spend hours on a piece like this without reading it once to check for basic grammatical errors.

The point of the piece doesn't seem to be to add anything of value to a debate, rather than to grab some easy traffic and make a joke. Whether it succeeds at the latter is up for debate, of course, but given the aims, who cares about the grammar?

We should certainly proof the article better, but it was an experiment. We paid $150 for the graphic, it was done and an overseas fellow in a couple of weeks. I sent him three emails so the overall work was about 15 minutes and cost 150 dollars.

Fair enough - I clearly missed the point. :)

That's why it's so funny: that's exactly what infographics do.

This post is textbook satire.

EDIT: see my sibling for proof.
