I have finally gotten around to adding proper pages on this site to provide information about my WordPress plugins. It’s still a work-in-progress, but it’s at least at a point that they are useful. When I get a chance, I’ll document the methods I used to automate things. But basically, I’ve created a couple of page templates, and I’m using the Plugin Info plugin to automagically bring in plugin metadata from the wordpress.org plugin repository.
The main Plugins page lists each plugin, with the plugin name and version, number of downloads so far, and an excerpt of the plugin description. On each plugin detail page, you get the full description, changelog, download link, and other stats, such as the minimum and last-tested WordPress versions.
