right now you can get lists of public notes, user profiles, and individual notes with replies. we’ll soon be adding the ability to post notes and get friends-only or private notes. check out the api documentation to find out more details.
this is definitely a good step for pownce (towards bringing it in line with other micro-blogging platforms) but i’m still left wondering what to use the service for. twitter (even with all its drawbacks) has a larger user base, is less buggy, more light-weight, and already has a slew of api-based applications that i can use. furthermore, the one reason why i was using pownce (as a digg-messaging service) was made redundant once the digg team added shouts to the latest revision of digg.
