Sure, I can elaborate. The article assumed a little bit of familiarity with Zapier. The basic mechanics are creating a new Zap on Zapier (which is a pair of one trigger and one action).

For the trigger, choose "GTalk" and "New Message". Specifically, the Zap will trigger whenever you send a message to our always-on bot.

You can pick any action that suites you, see the article for ideas.

We'll automatically perform the action whenever the trigger occurs.

There is a lot of flexibility in the system but that's the 500 foot view.

That's really cool -- certainly very nifty for Zapier users.

The title, though, implies a service (or hack) that isn't dependent on any other system -- maybe it might be better titled "Turn Gtalk into a Command Line for the Web using Zapier" or something?

Good call! I've updated it.
