Back in August I released a WordPress plugin for showing a FeedLand river — the stream of items from the feeds a FeedLand user subscribes to — on a WordPress page or post. As of yesterday it's officially published on the WordPress.org Plugin Directory:

https://wordpress.org/plugins/river-embed-for-feedland/

That means you no longer need GitHub at all. From your site's dashboard:

1. Plugins > Add New, search "River Embed for FeedLand", install, activate.
2. Settings > River Embed, enter the FeedLand username whose river you want to show.
3. Drop the [feedland-rivers] shortcode on a page, post, or widget.

Everything from the original post still applies: it fetches the river server-side and renders it in a sandboxed iframe, so it can't leak feed content into your theme and your theme can't clobber its styling. No third-party fonts or scripts. You can show more than one river with the username, category, and server shortcode attributes — see the live example I've had running since August.

Bugs and feature requests welcome on GitHub issues.
