An interesting viewpoint however it will pan out industry by industry for their specific requirements.
Without giving too much away I am in the process of constructing a ring of 8 .eu domains. Why am I doing this?
Quite simply my industry uses 7 widget products each one of which has from 500 up to 5,000 primary sources worldwide, note primary as in before even being processed in one of 100,000+ companies worldwide.
Domain #8 will be the .eu directory news site, as opposed to the .com news site, for these 7 widget sites.
The reason for doing it is this:
directorysite.eu - already #1 at .com - brand recognition
widgetsites.eu - instantly recognisable and memorable English name for each sector in the industry and nearly all in the trade know these names globally.
Therefore you can appreciate that when considering purchasing a specific widget that it would be easy for anyone to remember one of their own industry names for a trade site for an immediate quick start with an easy link across to any of the other sites should they require.
So instead of having:
they only have to remember ANY of the widgetsites names.
I have been fortunate enough to get these very nice .eu domain names since the .com's have been taken up by all sorts of non-trade related companies. I also happen to have the .info names which I use for...guess what, technical trade info and also the .biz names which we use for...guess what, business trading and forum boards etc.
Now why would I chose to use .eu when I already have the above?
Quite simply that the "general" USA/Canada widget trade is completely different to the "general" European trade consequently I want to keep them separate.
I hope that briefly explains my rationale.
Anyway, it will be interesting to see how it pans out.
