Hi I want to develop some applications for instagram crawling. Here some questions: 1- I am experienced in c#, will that be enough?, or should I learn a different language from sctrach like node.js ? I mean will it worth it to learn something new? 2- As far as I know instagram API is restricted, like you can not post to instagram using instagram api. So should I learn instagram API anyway ? Or continue by just webcrawling ? 3- What other technology or tools should I check ? 4- What documentation should I read ?
