I'm using the twitter api to get data on many twitter accounts, because of the rate limit and since i can't ask the owners of all those twitter accounts to authenticate, i've to create several applications on my developer account (note that i'm already queuing and combining requests, i've used all best practices).
My question, what's the maximum number of applications allowed per developer account? i didn't manage to get this answer anywhere on the web nor on the twitter documentation
First of all, you should NOT make more than one Application for one application.
You need to handle data logically. Cache the data you are requesting so you can limit the number of requests to twitter's API.
