Primary G+ posting topics, in no particular order:
1) Software development (my own, mostly) and the occasional forward in the genres IT, science, and tech. (Formerly, anyway - elbow nerve damage caused by too much programming(!!!) has reduced programming posts to near zero.)
2) Pen/paper gaming topics, most of them about board-gaming in the strategy/tactics genres.
3) The normal range of typically geeky/nerdy topics, e.g. Firefly, comic books, quotes from and thoughts regarding various authors of the sci-fi/fantasy genres, and so on.
Notes and caveats:
A) If you add me to your circles, that does NOT mean that i will automatically add you back. i will check your G+ profile; if you post things that interest me, i will add you back, otherwise i will most likely not. i'm not in this to gain followers, but to share information.
B) i try to keep politics and "life choices" of all types out of my posts (e.g. religion, sexual- and biological/dietary preferences, etc.), but on rare occasion something mildly divisive may slip through. (If _you_ post _primarily_ about politics or religious matters, i won't be adding you to my circles, as few topics are more divisive than those. i mercilessly remove people from my circles whose posts primarily fall into those two categories.)
C) Nonetheless, _all_ posts are kept "family-friendly" and i _never_ post about highly-charged political topics (though sometimes highly-charged _philosophical_ software development topics, like the utter braindeadedness of the definition of "REST").
D) Most posts are written in English (a bastard mix of U.S. and The Queen's), but on rare occasion a post or forward will be in German.
