I was trying to reduce the number of queries my blog is doing, because I keep hitting CPU limit. I didn't realise this (otherwise awesome) plugin would do queries whilst the blog was being viewed and blog-posts being displayed; but by installing WPDB Profiler I saw a few MySQL queries.
I disabled the plugin as a consequence.
Is there any way you could make this behaviour an option instead?
So, if a link is broken, don't re-style it in the displayed post (I presume that's what it's doing on post views).
