Another example (to bury the prior example quickly ;)

Another long tail example of how people are using spreadsheets on the web... planning their housework... One spreadsheet describes "how to have a clean house (and dinner on the table) in 2 hours a day" - and is linked to from Miss Practical's Blog Post.

Scary part is, this isn't actually a long-tail example.. I've seen it too often... there's a whole community of OCD sufferers who organize their chores this way... Miss Practical actually seems to just be trying to improve her productivity, but the people at "Fly Lady" seem to be the OCD crowd... and one of them suggests using this spreadsheet to organize the housecleaning parts of her life... (yikes).
