Creating the buzz

It is always the last thing you think of, or at least it is the last thing I think of: Creating a buzz around new intranet features.

Our current routine for a new "major" feature is to create a "spotlight" that includes an image and/or screenshot, header, text and link that lives on the intranet homepage for three or four days. We also create a blog post on our "intranet news" blog that gets a few reads ( < 1% of employees ). We try not to send out mass emails since people don't read those from our HR department now (that leads to another future post).

What are your ideas about building buzz around new intranet features?
