Robert, I think you are mistaking about Russian folks interest in NII. For my understanding, problem in another direction: not much Russian people, can make relation between NII and AP, mainly because of the Soviet education - all of them thinking NII lived in Winter Palace (primary residence), and has been evicted during 1917 February Revolution from his primary residence.
In most of the Russian People mind, Alexander Palace, sort of dacha, and after February 1917 prison for his family, significance sort of not exceeding Epatiev House (if some one know about it at all). Unfortunately information what we have here on this site, only few folks in Russia understand, and care about.
I am not sure, how many people can agree with me, but modern Russian person in Russia, care mostly about money and possession/collection of goods. Life for education, moving science and world knowledge forward, history preservation becoming extinct quality for Russian folks. Careless mindset can be seen everywhere, start from condition of Alexander Palace, going to quality of the roads (from road engineering perspective), pollution level, bribery on all official levels, way how people drive, care about job and each other etc.
I am not trying to dramatize situation, but I am looking in to that from realistic point of view. I know my point of view, often create a lot of turmoil here, but if I can't speak truth - who can?
I have from last year close to 1000 pictures of Tsarskoye Selo parks and palaces, Alexander Palace on most of them looking not far from 1944 photographs, and what scares me the most: folks who care about it - here in this forum, Pushkin citizens and Russian government officials accepting situation as is.
