why join a social network?
I have just been sent a link by a colleague that I thought might be useful. It is an article of comments by professionals on social networking, and the comment below is from an RSA Fellow, Julie Howell. The article can be found here
In a nutshell, she says that conventional social networking sites are of little interest and without some 'added value' over and above the opportunity to meet and greet she would rarely use them.
So that may be where membership organisations come in. The ability to offer social networking with the added bonus of... initiating community projects, professional and personal development, skills sharing... the list could be pretty long.
