I have yet to meet anyone who has ever heard of this place in the real world.
You don't have to tell them your username and problem solved.
All my IRL friends that are into crypto know that I am active on bitcointalk as I tried to "recruit" them, but I shared my username only with the few closest ones that I know for like 30 years. Unfortunately, I wasn't successful at all in my attempts to bring few crypto enthusiast here that I think would be a good addition, and some were active long time ago but have no intention to come back ever again, for various reasons.
This has been my experience as well. I’ve tried to get acquaintances to participate here and learn about Bitcoin. They all pretty much go through the same pattern. They join and try to learn. Their questions are usually met with snarky responses so they attempt to offer goods or services that they provide for dollars that they are familiar with, get called attempted scammers and harassed, then never come back. I’ve watched this happen so many times. Lauda and Vod alone are probably responsible for chasing away thousands of potential contributors here over the years. It’s crazy to see the moves made to empower users who literally go around trolling contributors here. It’s like we’re actively trying to maintain a good old boys club to be a echo chamber of yes men around those who are failing us all.
