I would aim for 100% and consider it a failure if it's any less than 99.999%. Curation belongs on blogs. >I see what you are saying about interests. Just thinking out loud, perhaps some sort of option is rather than followers slicing up a user's posts, maybe posters can purposefully create subchannels for partial subscription. This really is a semantic issue, not a philosophical one. I just don't see being able to ignore one aspect of a person's interests to be "slicing up a user's posts." I don't much care to discuss politics with my father-in-law, but I eagerly listen to anything he has to say about orchids. That doesn't mean I'm not 100% committed to him as a "friend" it just means he has interests other than my own. Likewise, I'm interested to hear what anyone has to say about orchids, regardless of how well I know them - and maybe, through affinity to orchids, I'll discover we have other things in common. You see "fragment." I see "aspect."
