are all oauth 1.0 api's supported by oauth 2.0?

[deadcoder0904]

is there any place where there's a comparison of which oauth 2.0 methods are supported?

i'm assuming that you can't use oauth 1.0 & oauth 2.0 in conjugation so if 2.0 doesn't have some api available then you can access it via 1.0? is that true?

helps me decide if i should go with the new 2.0 or the old 1.0 :)

OAuth 2 (user context) is restricted to v2 API.
