Questions

What can be tagged? People, photos, videos, music, websites, blogs, articles, forum topics, groups, events, announcements, advertisements, etc.
How will this help people? Allows people to search by topic rather than by media.
How do we maintain authority? Being the central repository of tags, but that also means making these list of tags available for other websites to utilize.

Redundancy: Tagalag tags people. del.icio.us tags websites. But some websites are blogs that are published by a single person. So that means I have to use the same tags for the person, and her/his blog.
Existing Services: Not everyone will migrate to a new system. We must provide a service that will work in conjunction with existing services.
