I feel honored that you think it is worthy a whale's attention - thank you for yours!

You raise another good point I forgot to mention: substeemits (analogous to subreddits) would, of course, be terribly impractical, but it would at least be nice to have a tag subscription list or something of that sort - ways to group my interest. The protocols (#agot? #gameofthrones? #asoiaf?) would probably evolve organically.
