A tanking job market is turning into good news for business-focused social network LinkedIn. Despite a 10 percent staff cut (36 people) in November, site stats are up. Page views increased 9 percent, invitations sent were up 10 percent, connections jumped 11 percent and member recommendations were 14 percent higher since September 2008.

Not surprising given the site’s growth. About 1 million people flock to the network every two weeks now, compared with half that earlier this year. Linkedin has 33 million members compared with 8 million two years ago.

CEO Reid Hoffman told USA Today that the increased usage should help LinkedIn lure ad dollars away from competitors like MySpace and Facebook. “LinkedIn is the office, Facebook is the barbecue in the backyard, and MySpace is the bar,” quipped Hoffman.

To reach new users, LinkedIn this year revamped its site, adding a recruiting service for human-resource departments, a survey application for market research firms, a new search platform, mobile service, company profiles and a redesigned home page. Plus Spanish and French versions of the site.

A study by Anderson Analytics of 2,000 LinkedIn users found some interesting data:

— Nearly 60 percent of users have high personal incomes and either executive or consultant titles.
— Users with incomes of $200,000 and $350,000 are seven times more likely than those with lower incomes to have more than 150 LinkedIn connections.
— Executives make up 28 percent of users, with an average annual income of $104,000.
— Consultants comprised 30 percent of users, with an average salary of $93,000.
— Casual or new users had incomes of $88,000 or less.
