There is absolutely nothing wrong with this. It's actually completely fine, and good, for people to voluntarily form social groups based on a shared interests and traits. The movement to oppose this sort of thing has been a large factor in the deterioration of social life for many people. You are not entitled to membership in a community of close-knit friends.
I was just bemused at the webpage bragging about hosting a "24/7 LAN party" but then not even mentioning what games they like playing
> it sounds like one big "no girls allowed" kind of treehouse
They're just sharing the idea because they like what they've built and think other people could have fun building something similar. It's like a treehouse enthusiast putting some pictures of the cool treehouse they've made on their website. It's not an invitation to come and hang out in it.
I'm tempted to make one of these, TBH.
At which point you might (reasonably IMO) complain that you're rather curious what use they find for said treehouse in practice.
Whereas if they are captioned "this treehouse is my absolute favorite place to hang out" or "everyone should build one of these for themselves" or "building this treehouse saved my relationship" or whatever then I am going to find myself wondering why that might be.
Like if I tell you that Python is just the best language ever and you ought to be using it for approximately everything you do because it will improve your life or society or perhaps even the universe as a whole, might you not wonder _why_ I think that?
I'm clearly in the target audience as I'm now considering doing something like this. The page gives me all the information I need or want.
> around half of the people on the LAN have thermal receipt printers with open access, for printing out quips or jokes on each other’s counters.
> there’s a 3-node IRC network, exotic hardware to gawk at, radios galore, a NAS storage swap, LAN only email, and even a SIP phone network of “redphones”.
The above is from the linked essay about the current sordid state of the internet. It gives a few ideas for fun pastimes but honestly not a lot. Gaming with close friends is probably the majority of what I'd use a LAN setup like this for so naturally I'm left curious what I might be missing out on.
If the idea of setting up one of these doesn't sound like fun in its own right, I wouldn't recommend attempting it.
DN42 (https://dn42.network/) is kind of like this but public, mostly used to play with networking technologies though you could also use it to make a virtual LAN party.
Note: If you do, you should probably check the paths your traffic takes and get consent of everyone on the path, since most people expect to mostly pass network-control traffic and some nodes have very limited bandwidth. Fortunately, AS-paths in DN42 are usually quite short. If all your LAN party traffic is confined to your own network then obviously it's not a problem.
If you built one of these you could also connect it to DN42 as-is, being aware more people will be able to access your network if not firewalled.
When you join TPL you get a generated LaTeX document with all your connection-specific details. That document breaks down kind of _everything_ you need to know to join, and then you're paired up with one of those primary backbone people to connect.
