My experience using social networks

Social networks offer a way to connect with people both personally and professionally whom you may otherwise never have the opportunity to meet.  I find that LinkedIn and Twitter are the two social media apps that allow me to stay more connected with those in professional circles.

I use both LinkedIn and Twitter and find both apps extremely useful in learning about experts in a particular field of work.

Both services offer a way to connect with people and organizations that are affiliated with other similar "influencers" -- be it people or organizations.

The type/quality of "followers" on Twitter and/or LinkedIn does help to provide a bit of insight into both the quality and qualifications of that social contact and their sphere of influence.
