Well, we have a solution to this, with the new tags and notes features. You can add tags to each of your friends and write notes so you can remember how you met them or came across them (or use it for whatever you want!)
You can do this from with in the stream by clicking on pencil icon, next to their picture:
You can filter the stream by one or more tags. You can also tag someone from their 'edit' page (for example when you first add them) and you can filter the friend's list by tags.
We have also introduced tabs into some more areas of the site including the stream as you see in the screen shot.
Tell us what you think about these features at http://groups.google.com/group/friendbinder
