Just remember industry interests. 100% of the big industry players have based their core portfolio upon .com, 90% (or more) of major companies have based their online presence on .com and .com remains the de facto TLD of choice for business and enterprise.
If .co.uk cannot displace .com in its own back-yard, what hope is there for .eu - which has neither the long-established track record of .co.uk nor the attraction of having a national domain name.
Don't forget SEO demands that you are displayed in the index of your core country with Google. Great, let's get a .eu domain because that will help us with all the millions of searchers using google.eu. Let's give up the chance to have our own country, give up the chance to have a .com to pick .eu.
The only companies or individuals using .eu will be:
- Those people with a sense of belief or trust in the European Union who wish to display this publically despite the high risk of upsetting many potential customers in europe (I had previously argued for .eur or .europe - .eu basically refers to the European Union political movement, not europe itself)
- New companies with no preexisting rights to their name with which they can dispute whoever has their name .com or .cc tld, and whom do not mind their name existing for another site in the .com etc. space
- Sites with names ending in .eu who want a new-fangled domain after deli.cio.us
- Squatters and others who believe that a company will buy the .eu from them instead of disupting it
- Companies who obtain the domain name to avoid the hassle of a squatter registering it and having to go through the dispute process. Note this is not true use of the domain name as it is just redirected or may not even resolve.
