Self-moderation of entries by categorisation (for filtering on friends lists)
Short, concise description of the idea
Users select a category for the journal entry they are making, ranging from "life changing", "important", "every day", "thoughts", "quizzes" for example. Friends who are too busy to read through the less important entries can then have LJ filter them so people can just keep up with the important events in their friends' lives.
Full description of the idea
There have been suggestions similar to this but I could find none on a self-moderation basis, hence my suggestion. It also encompasses several similar suggestions into one cohesive update. The best part about this is that it would be peer reviewed - people who choose to adopt this will encourage their friends to adopt it in a similar manner to the <lj-cut> tag. The filtering should work such that only posts of X category or more important should be shown. So for example if "Quizzes" was the least important category, "Every day" was more important and "Life changing event" was the most important then someone filtering on "Every day" would see posts categorised for "Every day" and "Life changing events" but not "Quizzes".
