Framing micro.blog as a gateway where "finding the person is synonymous with finding their RSS feed" is perfect, after all, the micro.blog timeline is a glorified RSS reader with social features.
But, once it starts getting more populated it becomes an unmanageable way of following specific voices so transplanting them to a traditional reader becomes a must.
I don't think that this approach without the minutiae is elitist, more a natural progression to being "post social" - we (as a society) tried that, took it to extremes, but I think that's run its course and it is time to focus.
This is also where I diverge from the full indieweb experience espoused by some where you must own everything and have it all on your own site. That level of control doesn't appeal to me and if it's not something I want to own it's generally not something I create and won't exist at all.
