Which are the most useful information/content blocks on an intranet home page? What are those functionalities requested by end users? - I am interested on past experiences...
It really all depends on the culture and size of the organization. However some past examples would include something like tip of the day.

Other items could be a stock ticker, recent management blog posts, rss feeds that are industry specific, the company in the news, links to common resources.
