the catalog is a good idea; I keep an index of fiction, and I need to recreate that for other topics.
another idea I have thought of is link-chains; maybe not a full index, but a series of related posts
I have also thought about mirroring my Steemit work on a wordpres or blogger site, solely for adding tag searches and indexes.
you gave me some ideas - you're a really good commentator, Steve - Thanks!
thanks!
