I do work for a number of companies and myself, not all of which can be posted on the blog to prove word count, but all of which are destined for publication. The key here is transparency.
Quest, my RPG which I'm intending on publishing later this year, currently has 57000 words written for it, and while I intend to count the words I do for it this year, only anything above 57000 words will count towards final count (and only when I publish it...). With such things as Call of Cthulhu and the works I do there, wordcount will only apply when the works are published (so they'd better publish on time), but that way I'm not losing whole swathes of the day doing works that don't count towards final...
