I feel like there are many devs out there who expose a lot of personal details and opinions all over the web. Maybe it's just me, but when starting out with the internet I tried my best to separate my personal details (name, age, sex, country, ethnicity, family ties, relationship status,...) from usernames in public.
Seeing devs do it willingly and voice opinions on divisive or sensitive topics kind of messes with me. Aren't y'all afraid of missing out on job opportunities if someone reads your opinions, code, or other stuff tied to your personal accounts? Or letting anybody (maybe family, friends, acquaintances, ...) in on your personal life, mindset, opinions and other personal information?
I keep different identities for different purposes. This identity is pretty public and active on social media, but mostly in the developer and anime sphere. This is partially born out of a desire to find other people to connect with on those topics, which makes it a worthy trade-off in my view. I also don't mind sharing what I've posted since most won't bother to look closely, and even if they do, there's not too much to find other than my interests and past projects.
Other identities serve other interests or are much more personal, so those things aren't as closely in the public eye. My more divisive or controversial takes are really only shared with trusted friends and generally not in writing though, so I might not fit the question you're posting very well, haha
