The hard part is dealing with Twitter's API rate limit and scaling. It's nearly impossible to pull down the data for large accounts like @aplusk. 5k id's at a time, pulled synchronously (due to Twitter's API paging system), by the time you're able to get all the data, he's already received 1k new followers.
Thanks for the feedback - Twitter does only return 5000 followers and following and I'll try to add support for high-profile people in the future. There is the issue of the 150 requests per hour limit that Twitter has per IP which means that it can't work on really big people without using a service like DataSift.
Have you actually read the DataSift TOS? I did, and it was completely unusable for what I wanted. (Last year, may have changed.) Basically if you payed them and extracted info you then couldn't make it publicly available. You also had to charge anyone you gave the information to. Which kinda makes sense, but rules out a lot of apps.
I don't quite understand the point of this. What's the benefit? Isn't this the exact same thing as going through my Followers list on Twitter and looking at which ones don't have the blue "Following" button next to them (which would give me the more interesting metric, people whom follow me but I don't follow)?
Apologies - I do need to do the reverse but most people follow more people than follow them. And yeah it is the exact same thing as that, but you can search it and monitor who's unfollowed you since you last saved your list. You can also track/check other people so it's more useful than just looking for the blue following button - which I often find buggy
1) Tweeps you're following but not following you back.
2) Tweeps following you but you're not following back.
3) Tweeps who recently unfollowed you.
4) Tweeps who recently followed you.
5) Tweeps you're following but haven't tweeted for the past 1 month.
6) All the tweeps you're following.
Hi, thanks for listing JustUnfollow. I made this about 2 years ago and we're 2 months away from hitting a million users... Last week we launched a native Android app and we'll soon be launching an iPhone app as well :)
