Can you provide a bit more explanation on to set up something like this? Is it a Zapier feature? The article just lists 5 faves and skips the "turning Gtalk into" part.
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.
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?
