I liked the post and then I un-liked it.. but it still appears in my dashboard.
I removed the like from this post (it was accidental) but I'm also as you noticed testing stuff :)
I agree on all points. I think just removing the activity would be the best approach.
Yes, I kind of figure it out.. I like the fact that you don't show the negativity so I wouldn't like tostart seeing you know liked and the disliked post right after the other.
BitBucket does that and it doesn't look nice.. the smarter way (and of course a bit harder) is simply delete (hide) the initial like activity.
