Social networking is my thing this year and I just wanted to share my strategy with you in case you find it useful.
I spend about 30 minutes each day managing my Twitter and Linkedin accounts and it really helps.  Each day on Linkedin, I search for others I can connect with. I also look through my connections and find people whom I can endorse and after endorsing them I ask them to endorse me as well. I added my social networks to my email signature so that people I communicate with will add me or view my social networks.
Weekly, I look for one thing on my Linkedin that I can improve and then I improve that area.  It may be adding more detail to a section or revising some wording but I make regular edits.  Next, I Google myself to make sure that no negative information appears about me and that my positive sites appear early in the search results.
Most employers Google potential employees and they check their Linkedin, Twitter and public Facebook so it can really pay off.┬á You can also search for jobs on Linkedin but it will only show jobs that you are connected with so as you add more connections, more jobs will become available.┬á I never would have landed the book contract if it weren’t for Linkedin.
