Susan,
You may be interested in the concept of reverse job searching which is an inbound marketing technique that requires the strategic use of social media platforms to attract interest and opportunity vs. only seeking opportunity. The primary idea is that one's virtual presence in virtual communities already allows them the opportunity to have dialogue and form relationships with targeted audiences. For instance, if my goal is to become employed in the graphic design industry, I may join virtual communities of graphic designers such as LinkedIn Groups, or niche social network platforms that allow me opportunities to engage with my target audience. Demonstrating expertise in one's field through answering questions on group forums, being helpful, and sharing relevant, valuable content either curated from the web or originally published on one's blog provides an opportunity to showcase one's talent, knowledge, professionalism, etc. In doing so, it can lead to attracting opportunity when done strategically in targeted communities where attention is wanted. You may find the following resources helpful to expand on this concept:
