If I _really_ cared, I'd never post publicly at all. Just trying to not be obvious who I am in real life. Every night when I plug in my phone and go to bed, I always say "good night NSA" because I assume I'm always being tracked :)

Yeah, totally agree you don't need to make it obvious.

But any smart, motivated actor can probably derive who you are from your posts.

You probably give away little hints about yourself, interests, tech you use, etc. Cross referencing with data leaks, public Github commits, LinkedIn profile, the time you usually post here (tells your TZ), etc, it's not far fetched to determine who you are...
