We are still pretty much at MVP stage but you can hopefully get a hint in our intro blog:http://hackerjobs.co.uk/blog/2012/3/25/when-jonny-met-stevie
Long story short, all job boards with a tiny number exceptions are catering primarily to the recruitment industry. Our priority is currently, and will always remain with the direct employer and the job seeker.
As the site grows we will be adding features that don't currently exist on any job board we know of with the intention being to elevate HJ to the point where people can use it as a more effective alternative to recruitment companies.
Once we have a more clearly defined timeframe for our future iterations, I'll create a blog post highlighting more details on how we plan to achieve the above.
