I'm currently designing a comments table for a site I'm building. Users will be able to upload images, link videos and add audio files to the profile.

Each of these types of content must be commentable. Now I'm wondering what's the best approach to this.

My current options are: 1. to have one big comments table and a link tables for every content type (comments_videos, ...) with comment_id and _id. 2. to have comments separated by the type of content their for. So each type of content would have his own comments table with the comments for that type.
