It's a shame the Amazon/Microsoft marketing machine is slowly killing the art of system administration. Though I guess I probably sound like a greybeard complaining about kids today and their fancy libraries and compilers.
When it works, it's great. When you have to 'prove' a problem isn't yours, and you send tcpdump files to the developer and partner company's networking team showing how the remote firewall is rejecting the packets, and neither of the recipients knows how a packet syn-ack sequence should work, or what this Wireshark tool is, it's sad.
That knowledge is becoming increasingly low level though as we build further abstractions over it. If you're working on a network you probably aught to know how TCP works, or at least know how to use Wireshark and a reference. If you're trying to spin up a simple webapp on AWS, you can pretty much stop thinking about firewalls and networking once you set up security groups/NACLs/policies/etc and confirm you can hit whatever is behind them. With new trends like immutable infrastructure coming into vogue, I'd even argue that system administration altogether is becoming a more niche skillset.
All the VPS providers are doing their part too. While Digital Ocean, etc. publish some pretty good guides on how to setup some software, step one is always "spin up a new VM on our platform". Based on discussions I see here and elsewhere, people seem to have completely forgotten how to install VirtualBox and run a local VM.
A listicle of networking guides. I guess this may be found useful by some, but it appears to me as buzz feed-tier tech writing with no content produced; certainly not what I'd expect from a professional outfit like red hat.
Mostly linux agnostic, but in case it helps, its was all right for me. The practice exercises at the end of each section offer some hands-on help with some linux tools
Lists don't make for such great discussion, because they end up being about the lowest common denominator of the items on the list, which is always something generic. Generic discussions aren't as interesting because there's rarely anything new to say about them. It's better to pick the most interesting item on the list and submit that.

maybe /u/dang will be by later if enough of us flag it, and can simply close the account.

Never. The same goes for Systemd too.
