My personal feeling about most of the Social Networks is that they are often a place for dissemination of soft Porn or a time waster that provides an alternative to actual productive, physically active endeavors.
That’s what I originally thought. But now there’s a very active conservative community there, including a FR group. Just about every major conservative columnist and writer has a presence there.
And it’s a very good way to disseminate conservative ideas to other FB friends who see your postings and updates. I think it’s a valuable and powerful tool.
