Update activity
How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.
Release cadence
Actively maintainedHow often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

What its installed base runs

Estimated value
What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.
Est. annual revenue
Est. acquisition value
No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from. The recent download trend is too spiky to read.

A good plugin that does something very useful. Love the indieweb and Matthias Pfeferle does such great work

Though I believe that both this and the other Semantic Linkbacks plugin should be merged, both are well done, easy-to-use and expertly integrated into WordPress. Easiest way to begin integrating IndieWeb into your website.

This is fantastic. I joined indieweb a few days ago. Last night I wanted to know “So what actually does the technical implementation of a WebMention look like?”. I am now working on improving my understanding and perhaps I’ll create some documentation that I find easier than the w3c spec or a WP plugin. Great work, very patient team.

Easiest way to integrate Webmentions!

Except for the conflict with Jetpack’s comment system and a quirky bug with emoji icons, this plugin works as expected. This topic was modified 8 years, 8 months ago by Khürt Williams.
