Is there any way to get better at black box testing other than targeting random things and/or doing bug bounties?

I'm not good or anything, since I recently started trying to delve further into web pentesting... However, I'd definitely recommend reading other hackers' reports. I've learned a ton recently just by doing that. Check this out if you haven't already: http://h1.nobbd.de/. It's a disclosure timeline for HackerOne.

Nice, at least someone replied (the guy above you did but he didn't know what I was talking about). This is SL so it's not like I expected much.

Lol, hopefully we can get some infosec related discussion started here again.
