We’ve had some discussion about DVMs although I think it still remains to be seen how best to use them.

Right now the plan is to build a relay kind of like purplepag.es that keeps track of all (non bot) kinds 0, 3, and 10000 notes. For free, a user can have scores calculated and stored for the entire network of 30k-40k pubkeys, and can also export subsets of the list using NIP-51 ranked from top to bottom in groups of 100 to 1000. Then you can play with the lists on other clients like listr, amethyst, coracle, etc. Then for a fee, you can set the NIP-51 lists up for automatic update every week, day, hour, whatever. 

Then the next step will be contextual lists. Example: gather together all NIP-51 lists named “Nostr Devs” and merge them together, but disregard any lists that are not vetted by the grapevine WoT score, which ensures bots won’t creep into the final product.

Now we have a grapevine-curated list of Nostr Devs who can be relied upon to curate more content. Lists of relays or nostr apps, perhaps.

Is there a role for DVMs in all this? Probably, although I’m not sure I’m yet 
familiar enough with DVMs to see how best to use them.
