Explanation of terminology for 'ping' in Chapter 1

[Japh]

I'm not sure whether you think it's necessary or not, but where you're explaining what a permalink and trackback are, you use the term ping (also jargon in this context) without explanation.

I would think if someone didn't know what a permalink or trackback was, they also won't understand what a ping is.

This might be necessary. Not sure though. @kristastevens?

Ping @mikedang who is working on Part 1.

@smckeown @kristastevens I agree that it's not necessary. My sense is that this is a historical look, and not a resource guide.
