I find it strange that you're able to read the "likes" you've received but not those you've actually given to others. For me, these posts are like the "favorites" that are saved, which I prefer to follow up later for review. Otherwise, what's the purpose? At the moment, I can follow particular forums or threads as well as particular members, but I can't mark and save particular posts. Note that I'm not interested in twitting those posts but merely seeing them within ET.
Completely agree. On other forums I 'like' a post, almost to keep as a kind of bookmark to go back too and read again at some point without having to 'subscribe' to the thread and then trying to find a particular post. Maybe as an idea you can 'like' AND/or 'favourite' a post, with of course being able to find them posts in your 'liked' and 'favourited' posts tab in your profile. (i'd then personally 'favourite' posts with the idea of going back to them)
