I think you just perfectly described why I decided against pursuing a graduate degree in philosophy. I did my undergrad in philosophy and religion, but having pursued a career in journalism, I've found that most of the relevant philosophical debates are taking place on blogs, social media, and the op-ed pages of major news organizations. And like you said, "most good philosophy is done in the pub." If/When I do finally decide to submit to the grad school grind, I decided that something in STEM, potentially comp sci or neuroscience, would be the best path for me.
Covering science, technology, and politics as a journalist has helped me apply my analytical skills in interesting ways, too, by primarily asking why things are the way they are. But because I've also focused on real issues, it's kept my questions grounded, so I'm not floating off asking whether or not holes exist. ;)
All in all, great piece, and I'm glad you're here. Upvoted, followed, and resteemed. Looking forward to reading more of your work. :)
