The net has gone crazy this week with hype about Google Talk, Google's newly announced and released Instant Messenging / Voice over IP product. But some big implications have not been picked up widely: open IM networks and pay-per-call voice advertising.

Yes, Google wants to compete with the hype that is Skype. Yes, it is making a direct competitive play with MSN, Yahoo and AOL's millions of installed instant messenging customers. And in both segments, it's coming from behind. Yes, it can sell ads on Google talk. But this is all "me too".
Voice over IP is the future. In fact, it's pretty much here now. The problem is, there's not much cash in these consumer-to-consumer calls: worldwide prices are falling anyway, and while the pure-plays can beat British Telecom on cost structure, at the end of the day it's a commodity product. Although it would be kind of cool / scary to be able to Google search your phone calls ;-)
The first really interesting implication for me is around open networks - Google is using XMPP, an open source, XML-based protocol which could in theory open up the various instant messenging networks to each other, something that Yahoo/MSN/AOL have resisted. Whether it will succeed in getting these opened remains to be seen.
The second is around advertising and in particular pay-per-call. The reason that Google and Overture exist as businesses is performance-based, pay-per click online advertising. I pay you to deliver a customer to my site. But still 90% of businesses would pay more for a phone call than a click. As an estate agent, car dealer or plumber, do I really care about clicks? Calls are much more valuable, and I'll pay more for them. Although it's early days and the business models are still evolving, start-ups like Ingenio and eStara are proving this. Try a search for "mortgage california" on AOLsearch and look at the Ernest Loans ad that comes up from Ingenio to see what I mean.
Google or Skype's voice network and millions of voice users, could be a huge strategic asset in pay-per-call for the next wave of online advertising, integrating web and voice.
Yahoo has announced that it has just started trialling eStara's pay-per-call solution on Yahoo cars UK and soon on Kelkoo too. This one slipped by with little notice, but is almost as significant in showing how the next leap in advertising's getting closer.
Is Google becoming evil? Maybe. Are they scatterbraining into lots of random industry areas without any strategic sense? In this case, probably not.
