I don't think Harry wears the cloak often enough for the Weasleys to notice it. Even then, a missing Harry could be caused by many things other than the Cloak - perhaps the Weasleys just missed him, for instance, or he could be out to lunch with Quirrell. They'd have to watch him as he put the Cloak on for it to be notable.

... Although, hmm... If memory serves, the interaction of Cloak and Map is discussed in canon. Does anyone remember how that worked?

Harry Potter Wikia says Lupin saw Harry, Ron, and Hermione under the cloak.

That never made sense to me. Four students built an artifact more powerful than a Deathly Hallow through which Death Himself cannot sense his prey?

It may have something to do with the fact that the legitimate owner of the Hallow participated in making the map, but the whole map itself is very overpowered for a group of 4 students to create anyway. If it was possible to create such a map, why wouldn't the Hogwarts authority create it ? It's much more likely that the map was made by someone much more powerful, and only slightly altered by the marauders. Maybe they just added the fact that's usually blank and you've to swear you're up to not good to make it work ?

That's probably why its origin was changed in HPMoR (where, as opposed to in canon, it was originally part of the Hogwarts security system and possibly made by Salazar Slytherin).

Wizards invent much less than they theoretically could, which makes them very much like muggles.
