Good question. If the scoring system works as intended, they will either lead to enough interesting discussion to merit upvoting (as with this one) or fade away

Good question. If the scoring system works as intended, they will either lead to enough interesting discussion to merit upvoting (as with this one) or fade away. Personally, I'm happy to see more science history stuff on the main page, rather than just tech/programming and startup/business stuff. (I was a history student, though, and I'm particularly interested in the history of science and medicine.) Go the extra mile, though! There are much, much better sources for everything than Wikipedia.
