Do you have a single username you feel attached to?
Or do you like to use different names for different occasions?
Edit two and a half days later:
Thank you all for answering my question! It was so interesting and fun to read all of your responses.
I really appreciate you for taking the time to write.
I drop usernames without a second thought if it suits me. I use different ones I think up on the fly most of the time. The only one that matters to me is one attached to my development activities in the FOSS community, and I might share opinions using it but primarily I use it to engage in discussion related to development so that people who know me in those circles know who they’re talking to.
