Articles on internet mostly in 2nd person?

I've always found that an article written in the third person usually has the most authoritative voice. The thing I increasingly find on the internet is that most articles are written in the second person. A lot also seem to slip between second and third within the same article. I think this is the case with a lot of the articles I've bought from writers here on the WF too (not a complaint, just an observation).

I know there's is a lot of well established and successful writers here on the forum, and was just wondering when you write an article for someone, do you automatically write it in second person? Is this what's expected nowadays from a client? Do you have a preference depending on the client maybe? Or where it's going to be published?

I know most people in general (as oppose to say a magazine editor) when ordering articles would never specify, or possibly not notice the difference anyway, so just curious to how, as writers, you deal with that.
