Why delete the :user_id from the :status hash on updated of a status?

This part of the video completely lost me:

if params[:status] && params.has_key?(:user_id)
  params[:status].delete(:user_id)
end

Why are you bothering to delete the user_id? Is it because it already exists in the resource and so you want to make the system more efficient?

Also, I thought the params hash was for retrieving data in the URI. How is it getting populated by my actions?

Not sure exactly which video you're talking about, but the params hash in Rails is automatically populated with the form/url parameters in the request.
