I really believe content distribution has to work this way, so much so that we've created a site (http://momeant.com) that allows you to enjoy content and then "reward" it after the fact. As Louis proved, audiences will support something they find value in, especially if the price is spread across a large volume of people.
Is that because you'd like to specify a job as being for design and development (as an example)? I ask because check boxes are used when multiple options are selectable, but we went with radio buttons to keep job types separated.
Yeah, there are definitely a lot of job boards out there. We just wanted to see if we could help the niche of remote workers by de-cluttering jobs that don't support them.
