Something that really annoys me about Dawngaurd is the fact you can tell nobody about the last Snow Elf. I mean really they could have added at least one scholary type NPC that would have a dialogue option about this. I don't want Dovakiin to take this secret to the grave . Is anyone else annoyed by this?

I see your point, but I also think that Gelebor wouldn't want to be swarmed by scholars / adventurers once word got out.

There is no proof he is the last Snow Elf.
He even mentions there could be more.

And if he was to go around ranting about how there is a Snow Elf in the "Forgotten Vale"
People would have no idea where that is, and even if they got close to him there is a possibility that somebody would want to kill him.
The Nords for example, they might want to wipe out the last of em'

Elves also live for hundreds and sometimes thousands of years.
And we have no idea how old he is.

I would like it, but if the Nords killed him.

If bethesda do not expand more on snow elves and make it so that he really is the last one I will be very disappointed, they have so much potential here.

How would anyone get through the forgotten vale let alone find it?

I have a feeling that the vast amount of quests and storylines that would follow the universal discovery of snow elves will be saved for more DLC or the next game
