The new version has these hearts on my friends list. I had no idea what they were. I also saw that some of the hearts were only half full. There was nothing anywhere on the client to indicate what these hearts meant. I eventually figured it out but this was really unclear. I suggest either improving the interface to something that will be much more obvious what is happening, or just putting an info box there to explain what's going on. Really, now that I think about it, the info box should just be there no matter what.
This also got me thinking; when someone new has befriended me (or followed me or whatever the word is), it would be nice to have a notification when I log in and/or an icon somewhere, telling me I should go and check this. I can then decide what I want to do about it -- befriend them, leave them as-is, block them, whatever.
