Minimal feature set

[vonwao]

We need to decide minimal feature set to make this usable. My initial list:

• User login/registration (now available thanks to meteor-matra-kickstarter). Would be nice to be able to login via github/facebook/meteor.
• Post and comments need more attributes (user, category, last comment timestamp, etc)
• Ability to edit post/comment.
• Post list needs to be loaded incrementally (infinite scrolling)
• Markdown/rich text editor
