Marco Arment said he's in touch with several developers and will choose one to be the official developer.
He noted that while several Android Instapaper clients exist, they use his iOS private API in addition to his public API, and he will only endorse one using his public API only (Can someone explain why that would be?).
i thought it was, but now that i look again i don't think it is. there was a story about papermill on theverge [1] the other day that heavily referenced marco's post, and i assumed that the point of all the marco references was that it was the endorsed app, but reading the article again they don't actually make that claim.
