@petebrown For indie web discovery we need all the things: blogrolls, directories, webrings and many web search engines with their own indexes that can filter out commercial pages and RSS feed search engines.
We have lost a lot of the underlying Web 1.0 infrastructure that supported many of the above things so, now, it's like reinventing the wheel each time we want to build a directory or start a webring. There is no money in this which may be both a blessing and a curse. But despite that, people are slowly building back personal websites and the stuff we need to run them. There is a huge difference in the indie web between 2018 and now. Hopefully we will keep it going.
