This article says it requires coding but it seems to me that the substance of much of what is described here could be achieved with a Hubzilla channel (although, perhaps, not so much a Zap channel).
I'm no developer but it seems to me that the Nomad protocol would be an ideal basis upon which to build a dedicated "digital gardening" interface -- less stream-oriented, perhaps more module-oriented, with each module occupying something like a plug-in "tile" on a page, capable of containing (and providing a window onto): wikis, photo albums, lists, tables, databases, maps, playlists, books/film/tv/music/performance reviews, discussions, artworks/photos/comics, videos, etc. -- each federated, each capable (where appropriate) of having a comment section attached.
