I'd like to filter out @replies from being reposted. But only when it starts with @someone, not when I mention @someone in the post. Is there a way? I'm trying to avoid having to add something like #fb or -fb to make some things not repost to Facebook.
One method that some people have used is this:
1) Your Twitter feed always begins your posts with "[yourtwittername]: '
2) By adding "[yourtwittername]: @" to the "Ignore" filter in your feed settings, you can exclude replies.
More info on dlvr.it's filters.
