New feature inspired by this post: the per-item nofollow tag. Or should we just kill it? It's one step short of content generated by Markov chaining.

Maybe instead of killing spammy stuff like this you could have a "convert to Ask HN" button. This post could be converted to Ask HN: Professors Who Blog? It would be more fun, too.

I'd say kill it or leave the post open without the link; nofollow links still indirectly benefit pagerank/SEO via increased exposure.
