Two facts are in evidence:
1. Advertising in social networks like Facebook doesn't work (doesn't work well at least). Conversion rates are some of the lowest in the industry.
2. Social networks are getting older. MySpace and Facebook are seeing growth rates among those 35 and above as some of the fastest. 55 year-old females, for example, are flocking to Facebook in droves.
Do you think the latter fact will influence the former? Face it, we oldsters are a bit more obsequious when it comes to advertising. I think we warm up to it more easily than our younger counterparts.
Or, in the social context, maybe not.
Regardless, it will be interesting to see statistics when such are available.
What do you think? Will age play a factor?
