• Check out the Wordpress Demo Site – A simple plugin converts tags on posts into octothorpes and allows admins to edit the list of octothorpe servers the site uses. Octothorpes are created with pure-HTTP method and displayed using vanilla javascript. No custom theme or css required.
• We think Octothorpes and Neocities make a great pair, so we put some Octothorpes on Neocities.
• All the hashtags on peep.zone are also octothorpes
• Bear Blog has its own OP server, and anyone with a Bear Blog can use it without registering first.
