My friend Guillaume (I recommend to visit his blog on the hospitality industry) made me aware of that networking site.
Whereas sites like Linkedin or openBC are generalists, wiwih is "vertical" and specialized in the Hospitality industry.
General vs Specialized
It leads to the very same topic of general vs specialized. What do you think?
Usually, the business models of social&business Networking websites are focused on the number of registered members: volume of contacts/members is very important.
In that case, Hsyndicate is specialized in the Hospitality industry.
I plan to register and test the interface soon.
