For responding to others:
I have an extremely boring job, which does not provide intellectual stimulation. Also, it does not provide human contact on a face-to-face basis - everything is via email/IM/phone conferences, for the most part, and the staff is distributed around the globe so I have never met most of the folks I work with.

Unlike the job, PC provides stimulation.
Like the job, PC does not provide face-to-face contact. So it is either better or same.

For my own threads: I look for personal accountability, support from others, a written record of my thoughts and feelings and the facts on my life, and many more. For practical advice on fighting fruit flies and boiling eggs.
