As I said in my review, this plugin is inconsistent. When it works, it seems to work as it is supposed to. The problem is, it doesn't work all the time. Much of the time, it reports the following error:
The Twitter API returned an error while processing your request. Please try again.
There is even a thread, on the StudioPress support forum, discussing this plugin (See: http://www.studiopress.com/forums/topic/twitter-api-error/).
I would like to see this issue repaired and would be more than happy to change my review, when the inconsistent functionality is fixed.
