It's true that the Elder Scrolls focuses more on exploration that NPC interaction, but there's a balancing act here. FONV does far more with NPCs and factions, but the world is much smaller. Bloodlines, an excellent RPG, had great NPC dialogue but it was a very tight world and many areas were railroaded. It's give and take, and personally I enjoy the variety.
I can see multiple solutions leading to less quests, but when half of your so called "hundreds" of quests are just paid exploration or fetch quests designed only to point players to the real quests, then I'm not too worried.
With Skyrim, you can go any way you want regardless of level and progress of the story. The dialoge os purly optional. You are not required to follow what people say, but if you do, you can't complain about where the story goes, because its just that, a story. One you are perfectly able to put down at any time no matter what.

every down point cited for other games is actually some kind of bonus or intended feature for Skyrim.
