Social media for job searching

Useful report about use of social media for job hunting in US (interesting because I don't think UK is far behind).  The opening stats are not well written but I think they mean:

• 84% of job seekers have Facebook and of them, 2/3rds use it to look for work.
• 35% of job seekers are on LinkedIn and almost 100% of them use LinkedIn to look for work.

Most interesting, one in 6 of the sample had found a job in 2011 using social networking (although the sample was from a recruiting software platform so will be skewed towards computer literates).
