Google Talk days are over. For all you Gtalk addicts – You abandoned MSN messenger first, then you quit Yahoo chat. Now its time to welcome Google Wave. It is awesome and it’s here to give Twitter and Facebook a hard time, although it is very well integrated with Twitter.

I’m not really talking about Google Wave replacing Facebook or Twitter. The question I have is, with such dynamic integration with Twitter, Facebook and other API based services, will you even need to log into Twitter via Twitter.com ever again to access anything? Already, with Twitter applications, I hardly ever use Twitter.com’s web interface to update my Tweets, its always some application.

Although Google Wave is coming out in a browser-only version, it’s just a matter of time before we’ll have hundreds if not thousands of applications developed around Google Wave. With the failure (or what they call a failure at Google) of Orkut and Google Friend Connect, this is Google’s attempt to regain a slice of the communication market.

I am interested in how it will integrate with Google search and other search engines and how it will affect Internet Marketing and SEO for businesses in days to come. That will probably be the deciding factor whether Google Wave replaces Twitter for businesses.

In a nutshell – Google Wave is a multi-stream communication system that integrates with Twitter, Facebook and other applications for seemless communication, conferencing, emailing and media sharing.

Only Google Wave’s public launch will tell if I’ll ever need to log on to Twitter or Google Talk again.
