I have some reservations mostly regarding exactly where the line is drawn between an aggregate and a derived work, the same problem which is so knotty for the FSF in regards the GPL.   But since we are discussing our own work and are responsible for enforcing our rights thereto, so long as we retain some semblance of sanity in drawing the line ourselves that should not be a problem.

I still have some problems with the commercial vs non commercial versions.   This is greatly lessened IMO if we use the share-alike as any commercial usage would be required to carry the CCLP notice.  The drawback is that if a commercial entity sees a competitive advantage in carrying an article then they are not going to want their competitors to be able to carry it as well.  They could still negotiate with the author for rights to carry it without the CCLP notice - and they probably would because of the vagueness at the line between derivative and aggregate if they wanted to carry it.  The flip side is that they would be less likely to carry it because any of their competitors could also pick up the comment or article.  

On a strictly personal weighing I would say let the moral overweigh it; go with the full CCLP. If I get good enough at writing that somebody wants a commercial version of something I write here with exclusive rights they can contact me to rewrite to expand upon or customize the version posted here.

I would change my vote to the CCL share alike, commercial allowed as Tim suggests.  Once again I have no strong objection to the CCL/NC but in general would favor the CCLP because of my moral belief in expanding the commons.
