A few thoughts:
1. I would never be so brazen (brave? have the guts?) as to try all of this. I would expect to be rate limited and throttled or banned or get a nasty letter from a lawyer or something.
2. The HTTPie thing was interesting. I am still not quite sure what that application is, but I am definitely going to stick with curl now.
3. They demknstrated a number of interesting strategies unrelated to tech per se like registering that new domain and getting people to add them as a guest account and making those fake posts on what I presume is a university message board type thing. I bet this is how people who are good at stuff like “growth hacking” or developing engagement numbers and such work. Pretty clever. Still makes me feel a bit uncomfortable.
A cool story. I was hoping the demo image would say “you at $300 of omelets” but I guess it is probably not that fine grained?
