I just found a new online tool that could just be ESSENTIAL for any business that is serious about using social media to reach its target audience.
Forrester Research's Groundswell Consumer Profile Tool will give you a "technographic" profile (think demographic for the internet age) of your audience based on country, age and gender. There are 8 categories of user and a link to an explanation of each category. More detail and analysis can be found in Forrester's new book "Groundswell".
Unmissable :)
