I don't know that #TildeClub will be around forever, but the sites are fairly portable, especially if I figure out a better way to do image links, which I think is very possible in both Zola and Hugo.

I worry more about managing my own hosting space and domains. I'm pretty good about it, but there's something to be said for not having that responsibility and instead relying on a shared system with the goal of democratizing web hosting.
