The naysayers are making the classic mistake thinking that 'time stands still'
They argue from the basic assumption that every business, organisation, individual has (of todays date) already got a web site, their perfect domain name, captured their niche etc...
Wake up guys!!
For those who have their perfect, branded, well used, profitable .com (etc.) I agree that they will want to use the strengths of that to capture mobile traffic using diverts & mobile.xxx.com etc...
BUT!
Minor oversight on the part of the naysayers is that;
The mobile web is barely out of the womb... let alone in nappies..
The entire Web as we know it today is still way way less developed than it will be in another 5 years (etc) there are still (globally speaking) more than half of all businesses (of all sizes) without an effective internet presence.
There are 1,000's of new company start-ups every week (globally) each & every one competing for domain names, marketing strategies etc..
The latest trends are to use multiple ID's to market & brand companies...
For a 'made up' example take the sizzling bacon company;
It has 'sizzlingbacon.com (& defensively reg'd other extensions)
It may well have had the foresight to catch... bacon.com breakfast.com baconbuttie.com porkproducts.com sizzlingdeals.mobi sizzle.mobi grill.mobi & other marketing targetted .mobis to promote it's brands, new products etc...
By the end of the decade you will see multiple niches being targetted by each company... this will create huge demand for the right names!
Now, lets look at how many bacon producers there are on the planet; 10's of thousands!
How many packagers & branded end user products.... 10's of thousands
How many 'perfect' niche domains are there.... at a stretch of the imagination.... every one of the companies may get to reg their name (assuming that all trade with a different name which is very unlikely - in factmost companies have at least one 'twin' somewhere on the planet)....
Then you have your marketing & branding domains! These will be in very short supply..... I mean just how many different ways can you think of selling bacon!!?
.mobi will be huge in marketing & targetted mobile niches... networking, dating, weather, financial, news, sports, food, retail, books, personal, email, in fact in most areas where we use the web most already...
research will be an area dominated by large screen PC's as will graphic work, video work etc..
Truth is, no-one knows what will happen next but I'm confident that marketing & promotion uses will dominate the b2b & b2c markets via .mobi & that the social aspects will also prosper.
The naysayers are assuming too much by not thinking outside the box, they forget that the world never stops, they forget that every day there are less choices of domains available (thats just a statistical fact) & I don't know how many .mobi's are regged but there are still an awful lot of good ones left! - I think many have regged dud names.... I know I have... it's a basic law of averages & in order to succeed one must fail.
The naysayers are great because they keep giving us hurdles to overcome... the points they raise have helped me refine my searches for new reg's, they have given me ideas for how the web may be used in the future & of course they will probably be right in some areas that they make their arguments.... my own portfolio is weighted so that in order for say 30% of them to succeed, another 30% may well fail - spread your exposure to .mobi & I believe you will do well out of it...
All IMHO of course & respect to the naysayers.... all arguments are valid until proven otherwise.
