What if Google plus and Diaspora can be combined in a certain way. Obviously they can't be merged in the real sense but they can interact with API's(Although google api is not there yet). Google has a service through which i can export data, and if Diaspora allows me to import that data it would be a major step for Diaspora which will allow consumer to easily shift. I think world would be a better place if there are two systems, propriety(Google Plus) and open source(Diaspora) while data remains under the ownership of the consumer.
I think the best path would be to learn HTML, CSS and Javascript and then you can use apperlerator software to create iphone app. I am sure this could be done in 4 weeks.
Since i am learning this stuff, i can do this for free. it will give me more experience, while you can have something done for free. Let me know. Thanks:)
