I have a client that want a website with a single domain name with many different extensions like :
somedomain.com somedomain.org somedomain.net somedomain.mobi somedomain.tv ...
Just to be sure the saturate the name and that nobody "hijack" the name.
The client is a Searcher in "Numeric content" and has a PHD in that field of expertise.
Personnally I think it would be overkill to go that road since the website will only attract a limited amount of people which will be refered mostly through official press documents and business cards with the web URL on it. Since he is a scholar I was looking for some published articles about that matters.
P.S. In the end if he is still convinced that his way is the right way I will do it, but since it comes from a public funded Grant I was looking to save him money (and the general population) so he can use the rest on more useful areas
P.P.S. I am from Québec, the most taxed state in North America, that is why I have those concerns :P
