Thanks for the moderate-comments tip

Thanks to an alert reader (maceyr) for telling me about the new “moderate comments” feature on blogger. I am pleased that Google quickly added this feature but disheartened that it had to. Discourse is good; censorship, not. Sploggers, though, are interested not in discourse but in cash, theoretically generated via click-throughs and customers who purchase products or services after visiting their websites. A splogger hopes to raise his or her site's search engine ranking by placing comments on blogs referring readers to their blogs.

When do you think that “search engine optimizers” will be considered the used-car-salesmen equivalent of yesteryear?
