You'd be surprised by how simple it can be to write such an article, when there's [i]no orginal research involved.[/i] What you're thinking of is someone qualified to write a book, or extensive article, based on their own research. That's not the same as a Wiki article. For example, I just wrote the following addition for the "Instrumentalists: 1920 to 1960" section, based on info from that book:
"Konstantin Kovalsky, a conservatory trained violinist with a hand injury that prevented his playing the violin, was likely the next actual thereminist in history. Kovalsky built his own variation of Theremin's design, with an additional foot pedal and buttons to control volume. He performed over three thousand concerts, many with Lev Theremin, around the USSR over the following fifty years."
Now, I assume that the Glinsky's information is accurate, but it doesn't really matter to Wiki - it's in a [i]published book[/i].
So I just reported what I read in my own words. Why do I need to [i]personally[/i] be a well-researched expert on the subject to do that?
