A while ago I started using Huginn, as a replacement for IFTTT. That’s going quite well. Huginn offers more features, integrations, and especially your chains (scenarios) can be as complex as you wish. IFTTT is quite limited in this area.
I use the Twitter integration to find certain Tweets. Now this does not only find native Tweets, but also finds every Retweet made for a native Tweet. Obviously I am not interested in duplicate content.
Huginn offers a way to filter out Retweets.
