I've no idea what is wrong with wordpress developers.
Their code was probably written with their asses.
Even the wordpress API is a big shit with very beautiful function names like "the_content".

Dont hate the player

That reminds me of a broken plugin I had once installed, that was fetching image URLs associated with a post. To see what's broken I looked at the code. Basically it relied on the way an older version of Wordpress was outputting image tags for every image associated with a post, and used string parsing to cut out the HTML part and leave only the "src" attribute. The reason it broke was because the new WP made some changes to an attribute.

That's Wordpress community for ya. Cancer. Have to make everything by hand instead of using readily built stuff. Including Wordpress itself.
