Company intranet

I work for a rather large company with its own intranet. It has some cool features. Keep in mind, I've never worked for a company with its own (well used) intranet before, so these may seem ho-hum to many of you out there:

• A buy and sell area, with 'items for sale' and 'items wanted to buy'
• A forum where you can ask the executive about anything (and we use it too)
• The cafeteria menus for the week
• The corporate phone directory (searchable by first name even)
• All policy documents online
• All human resources info online (including benefit info)

Does your company intranet have anything cool?
