NeoCities is an interesting web host. They self-describe as a social network of web sites, and to me they seem like a modern take on the old web ring concept. Before there were algorithms to be manipulated by search engine optimization, members of a web ring would all drive traffic to the each other by displaying links to the other member-owned sites. In the case of NeoCities, you only have to add tags to your site to categorize it into the appropriate web ring. As sites are updated, you see them in an activity feed. This is social media perhaps I could get excited about.
Web authors on NeoCities can only host static content, vastly different to the modern Web. Static content keeps a page loading as fast as possible, immediately served as-is from its home on the hosting service, to your local network and device. This is how pages used to be in the days of GeoCities and Angelfire, and though the 90s-design is optional, there are certainly great examples of nostalia-fueling sites to be found on NeoCities. Other site administrators go for a more modern, yet simple appearance.
The design is up to you, but the method of getting it to a browser is more efficient, so you're opening up the ability to reach people on lower-end devices or slow connection speeds. I like the idea of keeping pages accessible from all types of technology and all areas of the world. I can see static content being great for something like a blog or a fan site, perhaps a place to create some documentation, or a portfolio. At the time of typing, my simple sites would be good candidates.
For a free service, it's respectable that they commit to an ad-free experience. Upgrading to paid allows you to configure your own domain name, get subdomains for multiple sites, and you're supporting their mission plus you can obtain support if it's needed. But at $5 (USD) per month it still amounts to a very limited hosting plan with no FTP support, though there is a command-line file utility provided for power users. Traditional web hosts offer more flexibility, bandwidth, and storage space for less cash. GeekStorage has been my favorite for years. Once you pick a web host, you can use static site generator apps like Pelican or Hugo to generate your own static pages. But you're missing out on that inter-connected experience, the web ring.
This type of thing is right up my alley, but I'm not ready to do away with the convenience of using the awesome Grav CMS. It's important to make the distinction that Grav is not a static site generator. It does remove the need for a potentially slow database, and can be deployed with quite basic, bandwidth-saving themes like the one you're probably looking at here. My current host also costs significantly less per year, I can use multiple domain names and have fully separated sites, I can access the file system via Secure FTP, and the possibility of using dynamic pages and MySQL databases is always nice to have. But I love what NeoCities is doing, reminding us of the benefits of an old WWW, fueling nostalgia for some of us, and bringing new generations into the passion of publishing sites online and experiencing a taste of things before their time.
