About 18 months ago when I was looking for contract work, I signed up for Stack Overflow Careers. This was back when you had to pay to use the service (it’s now free but registration is by invitation only – more on that in a minute). The asking price had quickly dropped from an ambitious $99 a year to a merely illegal $9 by the time I signed up.
The Careers site has evolved considerably since it launched and now allows you to create quite a sophisticated online CV that aggregates your Stack Exchange activity, open source projects (GitHub, Google Code, etc.) and more. The idea of the service is that employers can search for candidates who appear to be good matches for their vacancies. All the enquiries I had were from companies developing financial software in London, which would have been ideal except for the work and the location.
Anyway, it seems that Stack Overflow is desperate for more people to sign up for Careers. When it went free-but-invite-only I was awarded 5 invites to distribute to suitable individuals. Last week I was given 20 more invites. Today I have been given two further batches of 20 invites. I currently have 63 invites available. If you want to try out the service for yourself, all you have to do is follow this link to claim one of my invites.
