And when what is fact can't be confirmed by someone else, does that make the fact posted less "helpful" even when it is confirmed fact by those in a position of authority or with reliable access to such authorities outside FT?

This "helpful" or "like" thing turning out to be helpful in any way other than by being a school-type popularity contest of sort or mere entertainment? I have my doubts that there is any chance of that being the general case. I expect it will just be clutter to my eyes after the novelty (of the popularity contest/games) wanes. Or can members disable this feature for their own posts, for the like/helpful counters, and for viewing "likes" if they care to do so?
