Google now indexes over half as many .info pages as it does .co.uk pages.
.co.uk 544 Million
.info 287 Million
.mobi has been heavily marketed and domainers have bought in to it big time.
Is it a bubble or the next big thing? I suppose it depends whether the marketeers can convince enough corporates.
The one thing that does come out loud and clear is TLDs take years and years to gain critical mass - or mass usage/acceptance.
There are no quick fixes for any new entrants be it .info .eu, .mobi or .asia. Or even for an established ccTLD that is latterly opened up at the second level (and for a massive economy) like .us
What we have been witnessing lately is just the "smart money" exploiting the huge potential of the mobile internet via the pump and dump of a domain extension. It would be wise for newer domainers to just stand aside and let the big boys and girls play their games because in the end, that's all it will prove to be.
Just like the stock market, the biggest players can manipulate and move markets thru their words and actions but in the end, after all the easy money has changed hands, it's the retail investor, the little guy, that is left holding the bag.
The the mobile internet does not need .mobi and neither do you :)
