If this were a list on personal influence and people who have caused a direct change in behaviour to other people (which seems like how some people are understanding it) it'd be nothing but people with weird posting styles (sbp, transience), those who made dumb words or fads (ertyu, kapik) and the likes of SHINE or HM who endlessly spam game details to influence purchases.
When you're speaking about influence to a community, a place, a unit, a complex mesh of things that isn't just a person the criteria to being influential is different. It's about creating trends, laying foundations that are later built on, stimulating the community and impacting on the entitys reputation. Memorable moments are a factor but it isn't ranking on those either.
Hope that clears it up, although I'm sure there'll be more Lopens with "dur hur dat isnt inflewanz" posts before the list is out.
