Got some potential questions I wanted to throw out, listed in no particular order. Feel free to pick some at random or throw them out altogether.

1. Social networking researcher Danah Boyd just published an essay detailing her belief that there's a growing cultural divide between Facebook and MySpace, in which white and more affluent people are migrating to Facebook, while MySpace is becoming more of a place for lower income groups and people of color. Does this assessment resonate with any of your guests?

2. Facebook recently opened up their site to 3rd party applications, which has led to a gold rush of people creating tools that allow users to aggregate all of their separate social networking tools (Twitter, Flickr, etc) into Facebook. Will this decision force other social networks like MySpace to follow suit?

3. One of the newest social networking sites on the scene is change.org, which lets people get together and form informal political action committees, raising money for and against political candidates. Do you think tools like this will have an impact on the campaign?

4. There's been a recent surge in do-it-yourself social networking sites like ning.com. They allow anyone to set up social networks on any topic they choose. Will these ultra-personalized social networks impact the usage and success of the big gorilla social networks?

5. Congress is currently considering legislation that would effectively ban access to social networking sites at schools and libraries that receive federal Internet subsidies. What do your guests think of this proposed policy?

There is such a hunger for real human connection in the world today it is amazing. I have been on MySpace for 3 years, first to promote my business to a college age audience and now I have found that sites like MySpace are a uninfluenced media. At age 32, I now have 3 MySpace pages along with facebook and several Blogs... The building blocks of this nation are connected by the free flow of ideas and the ability to debate issues openly. It's not for kids anymore...

I am a member of facebook and hi5. I am a grad student and international student so it helps me keep in touch with friends and family.
In fact I have met up with lots of people who I have not seen since high school, friends who are living all over the world now. I do not really use it to meet new people, instead for me it is a way of getting back in touch with friends.
I do agree these networks can be a bit segregated because people tend to add people they are used to. My network is entirely made up of JAMAICANS (and few are Americans and Africans I've met in person).

Jonpaul, almost all the major social networking sites are free and open to the public.

Hi,

I am the caller from Root Magazine: Global Dance Culture... hppt://rootmag.typepad.com

My cell phone gave out but I wanted to just say that social networking sites are a godsend for my business.... research, connecting, finding content and establishing my readership base.

Also - I LOVE the new Urth.tv for uploading videos.... but so far MySpace is great for finding new music, and Tribe.net if wonderful for talking to dancers and artist....

Cheers,

I worked in child care for years, so I have MySpace friends who are parents or even kids I used to take care of. I have to edit my site pretty carefully. Recently I found an autobiographical website that also has social networking capabilities (www.immortalspace.com). They let you organize your connections into groups, and you get to control which group sees what. Now I have somewhere that I can post pictures of my "weekend activities" for my friends to see, and I don't worry about these kids stumbling across them.

My approach to networking is all about business and helping people achieve their career and business goals. I.e. My choosing to network with you should not be taken as an indication that you may date my daughter. As business networking goes, LinkedIn is the most serious and has been very very good to me, allowing me to meet and develop reciprocally beneficial relationships with countless people the world over. As #21 on www.TopLinked.com, a website independent of LinkedIn that ranks networkers, I can tell you that I have amassed a world of business relationships. Feel free to invite me to connect!

What is the name/url of the site the guest mentioned which allowed he and his daughter to support a micro-business in Mexico? Are there similar sites to connect donors to other parts of the world?

Hi all,
Living in France let me give you a more internationnal view of online social networks.

As I listeen to your show it seems that this is a very devellopped systeme in the United States. Now of course most all of these sites existe in europe but the grand majority of people who use these sites are teenagers. I am stil surprise by the number of people I have to explain how to make an msn account to be able to just chat online, let alone have a blog or a network of friends on one of these sites.
People learn of the existence of these networks through spam mail were so and so invites you to be his friend on so and so site. People arround me (in Paris, France), for the moment at least, view these sites as intrapment sites were you give some information and they exploit it to the max, and you are then bombarded with spam mail. The french have not found the use of such networks yet, were the use in real life social networking is a national art, were information and opportinities are definied by the people you know.
I am glad to know that 5 years from now France will be were the United States is right now concerning online social networks.
