Curation on Hive is a leap forward from methods used on any Web 2 platform. A decentralised group of Entities, Large Stakeholders, App Creators and Guilds work tirelessly to promote good content and encourage creation and participation.

Curation on Hive typically is via upvotes (rewards) but also via education and encouragement (comments, discord).
In this post I begin with a brief overview of some of the well known curation guilds, I will also share some tools to help you discover some new ones, and see how rich our decentralised curation ecosystem is becoming on Hive.
A few of the best known Curation Guilds are
Curangel is a curation service rewarding curators and delegators while benefiting the whole Hive community founded by pharesim
1.9m HP is currently delegated to curangel from 271 accounts
Curie's mission to promote undiscovered and exceptional content. Curie is a meritocratic voluntary organization which supports the development and growth of new and existing authors. Founded by donkeypong the-alien liberosist kevinwong anwenbaumeister infovore gavvet steemship
386k HP is currently delegated to curie from 123 accounts. There are 8 delegations over 10 to Curie.
Curation Guild for undervalued, quality posts by newcomers and community building + onboarding and retention. Includes
@lovesniper OCD's Introduction Post Curation Initiative This is OCD's effort to give love to new users to hopefully retain them in Hive. Founded by acidyo
OCD curators go through many different communities to find posts to support. They also focus on promoting hive off the blockchain and onboarding.
457k HP is currently delegated to OCD. There are 21 delegating accounts 4 big ones. Roadscape is the biggest delegator.
Every Dapps on the ecosystem provide curation and the two biggest ones are
Most Dapps curate their user base as a way to encourage curation and some have built another layer into this process by rewarding token holders.
Hive is a rich ecosystem of nearly 3k communities. Around 100 of these are currently Active with over 45 posts in the last week. I have considerable experience in this space having managed 2 communities in the past on hive and their related discord channels. These communities may upvote posts, many produce regular newsletters and competitions and also have a sub-community living on Discord where you can promote posts, make friends and share experiences.
On Hive Curation is inextricably linked to upvotes (and downvotes). The more money a post makes the more visibility it gets. This may be the template model for web 3 platforms but there are other ways to get visibility on Web 3
I have been on chain for some time and knew ones like OCD and lovesniper but today I was browsing the curation tag and came across some other guilds, many of which I had never heard of.
The most notable ones can easily be found with some searches on the following app

Curation can be controversial especially when people are downvoted by a guild, large account or group of accounts.
I was running a community some years back and the approach we took was not to downvote but to tag posts with a comment if there was abuse. We also rewarded each valid post in some way just gave much more of a vote to the really good stuff.
On Hive there are many forms of curation and over the last few weeks I have spent some time researching the different groups and different approaches and there is a spectrum of approaches.
I built the following tool to look at votes a Guild (or Author) Makes on a Daily Basis (using hivesql data)

Taking a look at the first curation guild on the list 
I am sharing these tools in the hope these two tools are useful and you can discover new curation communities and support them to promote proof of brain and quality content on hive.
