www.google.com/ig is a very strange domain to begin with. Who would remember IG ? I mean - what's that?
Sure, it's easy to type, but on the other hand why not do it just
www.goole.com/i ?
That's even easier to type.
Anyhow, I think that many persons are confused by the name of the new Google product. They say on their web page that the meaning for this is one of these: interactive, Internet, personalized. OK, I ask: even they don't know what does this come from ?
