My conclusions are slightly different
It's true that in Europe people are more aware about extensions other than .com.
The local extension is often preferred to .com, at least for companies with local/national scope.
But if people 'shun' .com, they will shun other extensions even more.
For example .paris doesn't seem to be getting a lot of traction.
I think the problem is that the geoTLDs are competing against ccTLDs, and that is the
kiss of death.
Then you have the corpTLDs that are not available to the public anyway, and the generic extensions like .club or .cheese... these extensions are niche so they cannot appeal to anybody. These are not all-purpose TLDs.
There are just too many TLDs that lack
relevance, while ccTLDs are very relevant.
Again, those who are saying: it will take off "within 2 years, 3 years"... are very optimistic.
New extensions have been around for more than a year already. If 3 years is your investment horizon, you will be disappointed.
