Anyway, thanks so much for putting this together.

Cheers, Scott

Here’s my response to your interest in the ages distribution of Twitter users:

The age distribution of Twitter I think reflects a hunch I have that the 18 to 24 demographic is much more invested with the interaction provided by Facebook and is not attracted to the social media option provided by Twitter when they already have stronger social ties & stronger general affiliation to the network that exists on Facebook. If you check out the latest Facebook user segment growth stats information older and wealthier people are the fastest growing demographic on Facebook, but the 18 – 24 demographic is the single largest segment of Facebook (42%) and weighs in with plurality amongst the various populations.

Additionally, those aged 18-24 don’t have as much invested in meeting new business contacts as most Tweeters.

Aren’t the younger groups more heavily sought after by advertisers?

All kinds of segments are sought after by online advertisers. Within Social Networks, the developments with the last couple of months and growth in usage is throwing out of the window the notion that only younger people use these networks. What is starting to emerge and is yet to be consolidated is how these networks will enable advertisers to reach out to specific demographics.

How many social networking sites are used by each person?

A recent February research findings from InsightExpress would best address your questions about the number of social networking sites used by different people. The Stats I have included below help support my theory that those aged 18 – 24 who dominate Facebook, tend to subscribe to fewer social networks. While those who are older than 24 compose a larger segment of the group that use 4 or more networks.

“The Insight study reports that, of those individuals who participate in a social networking site, 71% have profiles on two or more different properties, with 26% having established four or more profiles.

Among social networkers who report having two or three profiles:
1. 25.6% are 18 to 24 years old
2. 23.3% are 25 to 34 years old
3. 14.7% are 35 to 44 years old
4. 15.6% are 45 to 54 years old
5. 18.4% are 55 to 64 years old

Among people with four or more profiles:
* 31 percent are between the ages of 25 and 34
* 14.1 percent are 55 to 64 years old”

Will younger users move over to Twitter, or are they already taken by MySpace and Facebook?

I think I started to answer this question in my first statement. In 2009 the growing usage of smart phones I think has the most potential for explaining any increase in the usage of Twitter since the media consumption that Twitter propels will be better facilitated on that technology. But what would stop them from using Facebook. The main difference between the kind of media that is shared between the networks I think is that Twitter is more related to current events relating to certain industry or social media trends. Whereas Facebookers share just about everything that their friends may be interested in reading/viewing.

Would it be feasible to bridge a marketing campaign over several websites?

I am going to have to ask you to be more specific about this question. Do you mean social networks instead of sites? If so, then yes, some of the most recent successful marketing campaigns (EG Jack-In-Box) have done this.
