"Best travel hacks" is hardly "intelligent conversation." I used to post about my areas of expertise, but I've found the general level of discussion on Quora has declined steeply over the last few years. So, yes, if "best travel hacks" is the kind of thing you want your platform to be about, by all means go there. There are profits to be made, no doubt. But personally I'm not going to bother with a platform that's filled with bad travel advice, discussions about how to game the interview / college admissions process, stupid questions about what celebrity X thinks about topic Y, and so on.
