After announcing the feature almost 10 months ago, Twitter is ready to start testing its "unmention" feature, which Mashable aptly calls the "ghosting" feature. It allows you to "remove yourself from conversations" you don't want to be part of. This might get annoying or overwhelming when you get mentioned in a tweet where tons of people reply and you aren't interested in being part of the conversation.
In theory, this feature will untag you from the tweet you want to be removed from. It doesn't look like you'll be taken out of the tweet itself, but it'll break the link functionality. So, it won't redirect to you. Twitter is testing out the feature with some users on the Web. It won't say how many people they're testing it with, but if you have it, let us know your thoughts!
