On the flip side of avoiding semantic confusion, it seems to make sense to make sure your site fits solidly into its definition. Wikipedia's definition is now the first Google result on a word I watch. When reading the definition, the two-word phrase my site is more specifically "about" is not covered in the Wikipedia definition. I wonder if it would make sense to add to the Wikipedia definition *or* make sense *not to*, being that as long as it isn't covered in Wikipedia maybe it avoids being lumped into the group (and whatever that now means). And, in viewing the terms emphasized and seeming (per Wikipedia) to be meaningful synonyms of this word, do you make sure you also sprinkle the symonyms throughout your site? If Google deems Wikipedia to be the authority, then it would follow that Google prefers to see other sites have a similar pattern of terminology usage.
