Write your own ‘blog’ / ‘wiki’ / ‘hypertext’.
Build interactive stories visually. Truly one of the best ways to teach an elementary-age child to write computer programs.
The most minimal and still very sweet way to participate in The Web. The child of watershed linksite Delicious, same conceit: post your bookmarks publicly, add a little note, a few tags. It’s like having your own href.cool! $11/year, but the real deal is $25/year and it’ll archive all the pages you link to.
The tilde.club was a 2014 resurgence of tilde-style user directories. You used to get these free at your university or with your home Internet connection in the '90s.
Yeah. Whatever this is. A bunch of fish, web fish I guess. Or pebbles maybe. THIS IS WHAT PARTICIPATING IS ALL ABOUT.
The very cutest ‘creative thinking and doing tool’—add notes to a page and connect them together with colorful pipes. (By @pketh.)
If you need to post something controversial or to subvert algorithms or bots for any reason, you can hide your text in these. (Hat tip, @foone.)
No, let’s not forget the TiddlyWiki. This is a personal wiki that you can edit and save on your own computer. If you need to put your wiki online, you can use TiddlySpot. A more polished but less powerful service can be found in Notion or notepin.co.
