I'm not sure. Some of the most informative pages were available under Tripod, written by people into obscure subjects. They were typically ugly (the pages, not the people), but were informative. They were a source of more interesting information than today's social network's "here's a picture of me eating something". You could actually learn something from reading the pages instead of just observing someone else's behaviour / possessions.
The home education community in the UK had a huge amount of information up on Tripod and similar sites, pointing to all sorts of useful resources for those who wanted to teach their kids at home. I'm not sure where they post information these days. Probably in Facebook groups.
These seem to be still around. Sometimes I'm looking for specialized info on non-technical software and there is usually a really ugly but highly informative page from an enthusiast around (who only got into basic html). (See bonsai care for example)
Actually, I meant that Minecraft is more interesting that the current crop of social networks. These types of pages are interesting, social network pages are not.
