So, let me get this right. New user's - the minority of users, find the stickies useful.
As an example, we have the 'frozen nav' sticky. It's been a sticky since the jurassic period. Surely, any normal person would just Google 'Lexus frozen nav'? The sticky is just unnecessary.
Fine, have stickies, but the content should be useful to the masses, not just 1 person out a hundred who somehow manages to freeze their nav screen (and is incapable of using Google or Youtube).
