Why is Voice of Apsu conj 3?

[jutetrea]

I usually get site searching set up early in the game, occasionally not first thing but usually. That extra 100 research right in the beginning is kind of a bummer if i'm playing a nation I usually wouldn't try to hit conj 3 with early. Difficult or very difficult research makes it much worse.

Just a preference, but I'd rather see it at conj 2 or even Alt 2. Alt 2 wouldn't be bad as it would promote the rainbow research for the rainbow site searching..everything but const.
