Once someone finds a conversation (blog post) they'd like to join, let them read the blog post, read the conversation that's happened so far, and then respond below it.
Besides the design (see below), the biggest part of this is the reply area. It should work similarly to the Write.as editor:
- Auto-save the text locally
- Support Markdown
Instead of a single "Post" action, present a choice:
- Reply here
- Convert to a draft blog post (go to Write.as)
- Send privately (via email right now)
In this task, we'll only address #1.
Store the reply in the posts table, content_type = reply. Then create a new replies table:
(Consider future attributes: muted, featured, etc.)
Show a link to the original blog post prominently at the top (aggregator site-style), and the conversation below.
