Ok, this post is gonna piss some folks off. It is not meant to and I hope my explanation stands on its own.
I never talk much about .biz as an extension because for whatever reason, my perception of the .biz extension is "Fly by night". I can't help that. It is how I think each and every time I hear a .biz. Call me prejudice. I can't explain it in words other than to say I know the type folks that bought into .biz. Another "Second coming" that never materialized. The "Z" crowd.
I hear .info registrations are down. That is not surprising. Domainers registered some of the worst domains I have ever seen under .info. So that accounts for the loss of domains registered. However, I still see .info as a viable extension when matched up correctly that might get a second look.
.TV is still a powerful extension matched with powerful end users. It is nt universal like .com, but it allows everyone in the world to broadcast their own TV shows and have it designated as such.
.Me is a nice extension when matched with a proper verb or noun that fits the extension. Again, limited but powerful.
.Org is for charities and non-profits and works best when match up to help the human cause.
.Net is an orphan that may get a second look with 700 .whatevers but still tough to build your main identity on without losing traffic/customers to the .com. Confusion sucks.
ccTLD's all have their purpose in their home markets. The minute that market spills over their physical borders, it is time for the .com
.Mobi is just a loser But with .mobile coming does .mobi get a second chance or do we have Loser #1 and Loser #2?
.Co, is simply confusion central and when the end-user or start-up, grows up, they will want the .com. Why? It will be cheaper and more rewarding to harness those already looking for them than the expenditure of advertising for new hit and miss business.
.US, don't write it completely off just yet. See if the 700 new extensions unfold the way each of these operators believe, than there is little question that the extensions already existing will also get a second look during that decision-making process.
.Com, King of the hill. An empire that will rule for the lifetime of every domainer and end-user reading this. It is just starting to gain traction not the other way around. But as always, marginal domains are worth marginally less today. When you buy slum property, prices don't go up easily. When you buy oceanfront property, you set record sales after record sales. The asset goes up and up. Simple parallel.
.Whatever, I will review each as they come to market. Most will be one word reviews. MeaningFUL or meaningLESS.
.Web, I would say the biggest open question at this moment is will .web be another .net or another .com? This is the most universal sounding name. This is where we get back to perception. Domainers won't judge the outcome they will simply BET on the outcome! HUGE difference! So if you don't look at it right, hard to get it right.
The best will rise to the top naturally. It won't be forced. The extensions will either be universal or limited in scope of combinations that make sense. There is an infinite amount of ones that don't make sense. Matter of fact, domainers have cornered the market on worthless domains. Sad but true.
.Aero, .Travel, are not even on the radar at this juncture so nothing much to say. I was seeing some .travel commercials last year, but have not seen them in a very long time. Indicating that the results were not stellar.
