Please give me the option to see a long list containing all of the people that I follow.
Showing me the users follow to followers ratio as a percentage would be useful data. If I could sort the long list based on this number, it would be even better.
I'm not sure about the current Twitter TOS, but having the option to bulk unfollow with a checkbox would make things fast and friendly.
1) The Twitter TOS does sort of prohibit this. We know this empirically because some apps that have done this before have been cut-off by Twitter.
2) It would not be scalable to users with huge numbers of friends and also it would take a much longer time to load and sort.
It really is a nice way to cull my followers. I'm trying really hard to keep my Twitter account topical and interesting. However, spending the time to go through each and every user more then once doesn't sound like a lot of fun.
