No, there wouldn't be, Tsarfan, it's as simple as that.
There would be interest from serious historians (as on this site) of course, on the reign of Nicholas and Alexandra, what happened up to and on the night of July 16, 1918, and to the whereabouts of the remains of the IF etc. but otherwise, certainly the zillion threads here and on other boards on "OTMA" and Alexis wouldn't exist. Nor, I imagine, would the number of "family albums" be around either.
