== Links to 's web site == 

 Hi.  I'm the person who removed Waabu's external link from Logarithm.  You conclude correctly that my action was caused by the conflict of interest, but the main reason is that the addition of links to this gentleman's web site was done on a fairly massive scale: some 18 articles was edited in one fell swoop.  Even though the site may be relevant for the various articles, I'm pretty sure that this action violates WP:EL etc., wherefore I reverted the edits.  Cheers.
