Our policy for official apps has been to play by the rules and not use “scraping” to try to get at stuff that there’s no official channel for. Reason is it could burn bridges in a pretty catastrophic way — for example, getting Tidbyt blocked from accessing official API’s, or even land us in legal trouble.
So basically, for Instagram, that means we can’t just access the follower count of any random profile since they are now blocking that for privacy reasons.
I’m still planning on doing Instagram follower count, but the official way to do it is that you connect to your Instagram account, and we show your follower count. We don’t have a way to get at the follower count for other people’s profiles, sorry
For Twitter, it’s a lot simpler. They make follower counts publicly available with their API so we can do that easily. Actually we already have a Twitter app in beta, could possibly add it to that (@matslina, what do you think?).
I really like the idea of having a multi-platform thing too, that would be pretty neat!
