You have the order right but I have questions ...

I want all those to exist. I want  to use 1 and 2.

- a Jobs board where you can offer your services and find people to hire, fiverr style.

This of course should be an open standard so we can finally get rid of fiverr and all the similar platforms with a protocol. Or do you plan to earn by building a platform?

- local feeds, where the app will present a feed based on locations and allow you to post only to people in your location.

While this would really be awesome, how do you plan to not allow me to post to a certain location? Proof of location is an unsolved problem and in an open protocol ... clients can reject messages from people that tend to travel faster than the speed of sound or something but you can't prevent them from publishing to different locations. And maybe you don't want to neither. Many of us are international and like to share stuff relevant to one city and another city next.
