Users of twitter and of twitter’s API are noticing issues with the social networking sites.
Requests made to twitter today are taking upward to 10-15 second if not longer for processing, and that includes those made via the API.
If your application or website is having problems you are not alone! Twitter has noticed.
On the bright side, twitter has also been trying to cut down on the spam by not including tweets from new users in their public timeline and by removing targeting accounts registered in bulk.
