Seems like LinkedIn is benefiting from the recent financial industries crisis. According to a post at Cheezhead they have had significant increases in registrations and in recommendations:
The site has reported a 17 percent increase in registrations in the last two weeks. They are now claiming to reach 28 million users, up one million from last quarter.
Reports show that memberships from people representing the financial sector have also doubled after thousands of people have been laid off or threatened with termination as closures and mergers usurp industry leaders and rattle the core of the sector.
The site also claims to have seen a 14 percent increase in recommendations, most likely a result of users scrambling to attach praise to their resume in order to find stable jobs in a worsening economy.
I’m sure that other sites are seeing an increase in activity from the financial sector as well (i.e. Monster, CareerBuilder, Plaxo, Facebook, etc.) Understatement—-I have a feeling you can find many financial industry candidates on these boards/sites right now.
