Organizing principles for identity systems:
Blog keyword and link clouds
(20070712)
I tried generating a basic 'keyword cloud' for http://www.ldap.com/1/commentary/wahl/ to illustrate the primary themes of the blog. Unlike a tag cloud which relies upon a manually-assigned set of tags, this uses a stop list-filtered set of words which occur in multiple posts on this blog.
Similarly, a 'domain cloud' of the domain names of outgoing a href from this blog.
I believe these would be improved if there was a visual analog for indicating the relative age of each (the time since the keyword or domain was last referenced), but haven't yet discovered a mechanism other than fading, which is more difficult to describe in purely text and would probably require an animated GIF or Flash to show the change over time.
