I may not have been the first to notice this, but the clouds you can generate with del.icio.us for use in websites and blogs can bring up an interesting perceived ‘profile’ about the user based on their tags.

For instance in my tag cloud below, one might think that i have more interest in ‘webdev’ than i do ‘human-potential’. Shoot. Guess del.icio.us could also be used as ’self-checking’ tool to see where i need to balance out my interests and knowledge.
