Developing an Instagram Crawler (Which language, which tools?)

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 ?

Hey,

C# is enough. If you will only crawl instagram, then you can do it from their website. But beware that you can't send so many requests on web as on mobile endpoint (which is i.instagram.com).

Their public API has many limits, that's why you should use their private API instead. There is a lot of information about this online, look for yourself.
