Yesterday I tested the Zemanta plug-in, but the page it hit on start-up caused a JS error. As they said in the comments, they fixed it - JS error is gone. Quick work, bodes well for the evolution of the component feature set.
-- or maybe not. A new quirk has appeared: after I inserted the image, a square followed by a closing tag has appeared in my editing window, looking at the HTML view I see it stems from the following code:
<div class="zemanta-pixie"><img class="zemanta-pixie-img" src="http://img.zemanta.com/pixy.gif?x-id=303e21bb-9ae8-46c6-aec3-beeddccc77ec" />></div>
When I put text after the glyph, and then tried adding an Article, my text disappeared. And the Articles are REALLY hit and miss. (Maybe they're using the machine-gun pictured above...)
