For Gabbers who like to understand how their software works.

Lists, which are arriving very soon, are technically a variation of the Home feed. And, your Home feed is filtered according to your preferences. Your Lists are, therefore, also filtered according to your preferences.

"Filtered" means muted words/phrases, whole domain blocking, muting/blocking a person, and that is defined by each of you.

Gabbers can adjust their Filters in Preferences.

For the filtering algorithm, see second attached image. That logic is what executes for every post going into every feed to determine whether the post should be inserted or not inserted into the feed/list.

I am describing:
- app/workers/feed_insert_worker.rb
- app/lib/feed_manager.rb

This is not an area where I will seek to reduce cost. This logic is simply the cost of doing business.

There is no 'machine learning' in here. You are free to define what you will and will not permit into your home feed and lists. There are no robots in here hiding posts or looking for 'hate speech' beyond what you mute and block.

This is the logic that determines whether you will or will not see a post. This is the code that applies your preferences to your home feed and lists.

@robcolbert Where have you been hosting the source code repository? **Still** waiting for it to be open so I can check it out
