I had asked this question of Augie once.
Not that I wanted Fluther to figure out what I wanted cleared out, @dappled_leaves, but that it would be nice to be able to highlight a bunch at a time or click on a bunch at a time (like with email) and then delete. Sometimes, what I’m following is no longer timely, for example soccer question or politics question, or it just no longer interests me. The way it’s set up now, it does take so long to “stop following” – it’s just as easy to just click on the question, and then be done with it that way.
It would be nice to be able to highlight a bunch or click on a bunch and then stop that way. I don’t want all of my Activity for you deleted, just maybe half.
