Like jbigelow76 mentions the AMA happened in the Disqus comments. I didn't realize some people might disable it, so I'll make sure to show them a message asking them to enable it.

Thank you, most people I know actually disable disqus comments as they do any service offered for free that is embedded on multiple websites. The tracking is just too obvious. Same idea with gravatar.

The AMA is in the Disqus comments

Ah - that makes more sense. I have Disqus comments blocked.

Same here and this is probably more common in tech circles than outside of them, making Disqus indeed a poor choice.
