LIFEHACKER.COM.AU - July 5 - RubyRadar is a local online site targeting high-income professionals. It currently verifies members manually, but is working on integrating LinkedIn to verify that members work in the jobs that they claim. The site is shamelessly elitist; only 5000 members have signed up, the average income is $200,000 a year, and you will eventually have to pay an extra “executive price point” fee if you don’t want your income disclosed on the site. Right now, the site is free.
