If I had to choose just three

My top three must-have internal comms tools for today’s workforce:

• RSS/news aggregator: employees should be allowed to choose the information they need and find relevant to get their jobs done 
• Blogs/Forums: people want to express themselves, connect with other like-minded people (or be challenged by out-there thought), share ideas, get their questions answered….and of course, this community would include the ability to post audio and video
• wikis: an easy to edit source of information, collaborative space, an enterprise reference to act as the cumulative body of knowledge of a company or organisation (I’d also include team wikis that would allow for permissioning and levels of security.)

If I got to choose three more:

• Social network: people want to connect, share ideas, find one another easily…in a work setting this isn’t just about getting together to share music, but to find the people with the expertise they need to help with projects and getting work done better (if you can’t afford to get this in-house, you can create bio pages on a wiki as a stop-gap measure…it’s worked well for me)
• Internal YouTube: Who doesn’t love video. It’s becoming increasingly relevant, especially in brand-driven companies. If you don’t  have video in your presentation, don’t bother.
• Internal Flickr: Especially for big multinational companies, photos are a great way to create a sense of community. It’d also be a good way to share assets instead of shared drives or emailing them. 

What are your favourites? What are you doing at your companies/orgs?
