I found it difficult to find a 2.0 website that did not just duplicate the ones we already know. And try and find one that is interesting enough to use as an example in a library context.
I don't think Pearl trees is that well known. Their website puts it succinctly:
Pearltrees is the social way to organize, discover and share the stuff you like on the Web. Use Pearltrees to keep at hand the stuff you find everyday on the Web, to discover new stuff in your areas of interest and to drive people through your web.
I think that there is enough potential here for the librarian to promote a number of products and items of interest for the users of the library. The sharing idea is useful as well as conneting with others who might have the same interests.
And it looks good.
