Google "cloud" tool shortcomings

Are Google docs and blogger cloud? Whatever.

Google docs:

• unintelligible URLs
• not clear how indexed they are - I do know that docs that I have "cross posted" between my wiki (mediawiki) and Google docs have been indexed, by Google, on the wiki, but not on Google docs.
• "It doesn't exist if you can't google it"

Blogger:

• no formatting in comments
• can't link to a particular comment

? permalinks ?
