I use the friends feature to help find comments from
people who generally leave good comments, but not
always marked as high as my threshold (so I don't miss
what they might have to say). This works pretty well.
Foes does not always work as well. I would like to see
an addition of an ignore list, or modification of foes
so that I would not even know they existed. (e.g. no
message they replyed to one of my posts, etc.)
