Follower/Following delays 5 months ago

We’re working to reduce the amount of time it takes for new follower/followings to take effect. Right now, after you follow or unfollow someone it may take some time for that action to be properly recorded and propagated throughout the system. As a result, you may run into discrepancies such as:

• follower and following counts are off
• new followings not showing up in your timeline
• seeing that you can follow someone you’ve already followed

We’re planning several upgrades to address these issues and will post more as we make progress.

Update (3:03p): Other inconsistencies in addition to the above also exist:

• device notification changes for followers (choosing whose updates you get on your phone)
• favoriting and unfavoriting of individual tweets
