DevRant may not have such a big community yet, but I wonder whether my coworkers have some posts here.
It would be quite awkward to ask, so I'll ask you.

Have you ever (by accident) met a friend or coworker on DevRant or similar platforms?

Not that I'm aware off...
There's a few rants / comments of mine that would easily identify me though 🤔

@rendezvous you really scared me, since your profile looks like a coworker, oh God

No, though I did see someone share a devComic once in the company slack

A few coleagues have found me.

Some people from other companies I was assisting with some of their projects found me here as well. They also found my rants 'bout those projects.

It doesn't bother me.

I’ve read a few comments from coworkers on rants before lol.

I have changed my username twice since other people found out.
1.5 year ago, when I joined dR, I told everyone to join. Everyone knew my username. Then the day came when I had to rant any my college and couldn't do it as they might know.
So had to change username.

One guy here still knows who I am but that's it.

Never, but I definitely worry about it.
