I thought they were applicable - especially considering how much information some people share about themselves on social media these days. I play my personal cards very close to the vest, but I have followed (and unfollowed) some companies that were very much personality driven online.
And between LinkedIn and all the other places people can go and learn about your work history and education and such, I think defining yourself as an expert or as being very experienced is definitely relevant. "Googling" someone is a well used verb these days.
I completely agree about the first impression thing. In the context of this survey, I read that to mean the first time they see you or your work represented - website, Resume, FAA page, that kind of first impression. I found the comparison and contrast of online versus traditional selling channels.
