The Guardian has launched a competition to find the best commentator on its Comment is Free site – competition details here. The winner will join the ranks of regular bloggers on the site.

Editor Georgina Henry says: “Prompted by those of you who have argued that not only is the debate on most of the threads not as bad as I sometimes make out, but that in many cases is of higher quality than the posts by some “professionals”, we are now seeking nominations for the best commenters on the site, one of whom will officially join us as a regular blogger.

This person should:

– be well informed
– write well
– provoke debate
– keep the standard of debate high
– engage with readers
– be witty”
