I find it annoying how social GitHub has become. Posting notifying others when I work on public repos. I don't care for my coworkers to know when I am up at 2am

I find it annoying how social GitHub has become. Posting notifying others when I work on public repos. I don't care for my coworkers to know when I am up at 2am working on open source. I also use separate accounts now. Vlan is a good idea. Doing that now. Thanks.
