I can't seem to get rid of the duplicate posts.
I have it set to exclude retweets and to scan every hour for #cookingtips.
It works perfectly the first time, but the second time it includes all of the same posts as the first one too. In other words once a post from a specific tweet is created, it's not being ignored on the next scan.
I had to use a less than ideal workaround to accomplish what I wanted to and would love to instead use your plugin as it is wonderfully made.
