hCard+XFN supporting friends lists

Welcome! If you have an account on any of the following services, you already have a list of your friends' hCards with your relationship to them in XFN which you can provide to other services to save time by either importing or subscribing to social network information so you can change it on one site, and have other sites automatically updated, rather than having to re-add/remove all your social network contacts multiple times every time you meet a new person, decide to unfriend someone etc.
