I suppose it's possible to call some of this an addiction... but I have been blogging and using various forms of social media for about 20 years, and the main thing I'd observe is that my time spent here is time I am not spending on Facebook or elsewhere... but I stay pretty cognizant of not obsessing too much over my time here...
For example, the post I just set free I actually wrote this morning with my coffee... mostly, and I finally got around to putting it out there, almost 9 hours later.
Thanks @denmarkguy for your input. I think it is IMPT to have a balance and you strike me as someone who has that.
