It appears a major glitch has surfaced in Twitter where many people’s follower and followee numbers have been cut in half, in many cases. This is evidenced by the numbers that appear on your twitter page. You’ll also notice, if you visit the page of a suspected unfollower, you’ll no longer be able to nudge/message them, confirming your worst fears. However, if you visit the direct message page, you’ll notice they still appear under the drop down and you can successfully send them a direct message. They will also see you in their twitter stream, so don’t fear!
Go to getsatisfaction.com and report this bug or ditto if someone else has reported it (many have). I suspect this is due to a database caching issue since they have started partitioning the application to make it scale better. Hopefully they fix it soon!!
It appears I spoke too soon! I just noticed that my direct messages page does in fact reflect a number much less than the followers I have; in my case, this is a reduction of more than 80%! Likewise for the number of people I follow.
If this is a catastrophic data loss where we will have to re-follow everyone we’ve built up over months or years, I suspect Twitter stands to lose a similar percentage of users . . . .
Come on Twitter!!
