Congratulations! 250 IS an awesome accomplishment. I'm hoping to be #285 if someone hasn't already beaten me there....
(As an added comparison, the fiction world these days considers a best-seller to be 10,000 copies sold; very few come anywhere close to this.)
David, Congrats on officially putting your plugins up on Wordpress!
My WP skills are certainly below that of yours, but I applaud you for making the effort on behalf of the IndieWeb. I'm happy to help test/bang on your plugins and give feedback, (and If I can to delve through the code to help there too occasionally).
One thing I notice about post kinds in the 1.3.0 version is that the number of post kinds is much smaller compared to the circa 1.2.X releases. Did you deprecate them? temporarily? while you work out issues on each?
On syndication links I notice that the resultant icons (on your site as well as mine) shift over a few pixels when hovering over them - is this by design or a quirk in my (our) CSS perhaps?
Congratulations again and keep up the good work!
