The Wealth of Networks has a wiki to support the book. What’s not entirely clear is if the intention is to develop an independent network of readers, or if it’s more of a way of advertising the book. The book is available for download. There’s a link to Amazon, if you want to buy the book.
Though there are clear emphases on the economics of Networks, there is also some useful information about the social side, see e.g. Chapter 10.
It seems to be structured so that each chapter of the book has a wiki page; from those pages I’ve skimmed, it seems that they’ve got both examples & counter examples for each concept.
