The social networks is new direction of the web. Different kind of social networks create different kind of possible relationship. For example the network that I have on facebook has a small overlap with the network that I have in linkedin.
An email suggestion pointed me to a new kind of social network called researchgate.
for my usage this will hold the network that I have in linkedin, but as for all the social network, it has to grow to become a meaningful resource.
On the technical side I saw that it’s possible to import your library but right now the format accepted is only XML. I hope they are going to implement also the support for a BibTeX import, so I can test the semantic engine and take a look to the papers it’s proposing.
