I've watched that website launch and develop with some interest. Without disclosing any particulars, does the site do well for him? I imagined he was raking in the dough, but if he's still your co-worker I guess that's not the case?
To be clear, my coworker doesn't run thisiswhyimbroke, but a site with a similar layout.
It's a little extra money in his pocket, but not something profitable or rewarding enough to do full time. (He also has a few other attempts that don't do as well as the camping one, and with the camping one the income is pretty seasonal).
