I should've thought of this the other day, but I've just added sharing actions to public versions of my reader such as unicyclic.com/indieweb. This Planet turned into a bigger project than I thought it would be, it now subscribes to 243 blogs from members of the indieweb community.

Also since indieweb is all about supporting microformats I've preferenced subscribing to h-feeds and h-entry's where available, instead of any xml feeds that may be linked to.
