If you were able to have any features you wanted in a web journal, what would they be? In the middle of some "market research

" for future use. Any replies would be greatly appreciated.
Examples, to start things off:
- Option of HTML.
- Integration of current Listen-To.
- Allow/Prevent Comments.
- Template system for easy customization.
- Search entries/comments.
- "Moods:" happy, sad, whatever.
- Categorize entries.
