We would lose many of the people Milky Way got - simply because of the length of a page. On Milky Way, 10,000 people who do a couple each and then decide it's not for them contribute 20,000 classifications. On OW, 10,000 people who do a couple of weather readings and then decide it's not for them contribute nothing.
BUT... I am very greedy for the few hundred out of that 10,000 who would get hooked enuf to stay and contribute a few pages. For that alone, I'd like us to get mentioned on that site.
