As mentioned a few weeks back, Dan Brickley chair of W3C's Semantic Web Interest Group will be in the city this week and wants to meet up with you the New York Semantic Web Meetup. Once I have a day and time you will hear more about the location etc.
We will look at and chat about The Friend of a Friend (FOAF) project:
"The Friend of a Friend (FOAF) project is creating a Web of machine-readable pages describing people, the links between them and the things they create and do. FOAF is about your place in the Web, and the Web's place in our world. FOAF is a simple technology that makes it easier to share and use information about people and their activities (eg. photos, calendars, weblogs), to transfer information between Web sites, and to automatically extend, merge and re-use it online." 
I hope to see you there
