Comment application

[preaction]

Create a comment app. Other websites provide their ID and a path and allows users to comment on that path

Rely on browser same-origin policy to secure this for now. Require that something like nginx be used to proxy requests. Later we can add key-based site auth.

Comments should be markdown. Create a file-based store to begin with? Comments should be anonymous. Clear all bad tags (Mojo might know how). Put rel=nofollow on all links. Allow replies but don't write a tree.

Later:

• Allow voting
• Allow sorting by rating, last, first
• Allow non-anon comments to be edited and/or recinded.
  • but keep them around to be referred to

Rather than do very repetitive things, we're going to use Mojo::Pg for all of this.

Comments will work like this:

• GET /<base_url>/<*path>
  • Get all comments for the given path
• POST /<base_url>/<*path>
  • Add a new comment for the given path

<base_url> can be just the base URL of the Comment app, or it can include a domain section.

The idea here is that we are a central microservices platform. Though we will have to study that scaling problem...

We'll need a Markdown parser as well. And we'll need to do that all server-side.
