If I had something to add to the Iraq debate -- in facts or reporting or perspective or wisdom -- I'd add it; I'd have added it long since.

For if we are not careful, weblogs will turn into catalogues of "what I think about..."
When people could publish their own web pages, they too quickly became catalogues of "my CD collection." As if anybody should care.
