Knowing that other people could see when I stopped motivated me a lot. The whole thing made me a better programmer too.
Were you self conscious? How'd it make you a better programmer? Did you talk out what you were doing?
It made me a better programmer simply because I was doing it more, so I kept encountering problems and having to solve them. I learned why more experienced programmers do things and don't do things, I got better at using GDB and started using valgrind etc.
Props to the "don't give a F let me broadcast all of it" mentality.
The worst that could happen is that people see I watch porn. But everyone does, I wouldn't be that embarassed. Slightly blushing though.
I don't have much sensitive data on my laptop. I mean passwords are blocked off. So what can people see?
OBS (the streaming app) does let you limit the window to stream. I did use Incognito for most of the streams. I did also make a separate Twitch login on my OSX but it was such a pain to re-login to stream that I never used it.
There's definitely a risk here but yeah it's a trade off.
That said, for random private-ish accounts I use Chrome user profiles. Safari does not have them.
Are you American?
Ads seems the most natural business model if you get it big enough. hotels, flights, car rental, all have pretty ok revenue potential through affiliate deals.
However, before you get to that scale, try out selling it as a widget (or something like that, or a spin off product based on the crowd sourced data) to tourist offices of cities themselves. It wouldn't be huge business but I think with right pricing, some customization and support work for integration etc, you could make it 10-50k per deal and scale the workload pretty easily.
Definitely a lesson a lot of the HN crowd (myself included) could take.
