Twitter: I follow Christian leaders I respect as well as a bunch of software developers and some software projects

Facebook: I have a small number of friends on Facebook, but I never use it for posting personal things about my life, just to follow people.

RSS: I follow a lot of software projects, software developer blogs, and some Christian leaders/bloggers. This overlaps with Twitter to some extent but more for interesting articles or product updates that I don't want to miss.

Reddit: I follow some tech and software dev reddits, but it seems like there are too many beginner questions rather than interesting discussions

Blog: I have a blog in the works, not actively writing on it yet
