The site touts itself as "Part bookmark collection, part reference manual, part Q&A site, it’s a place to get inspiration, shortcuts and answers."
Whether you're after online engagement techniques, strategies, examples or want the answer to questions, The Digital Engagement Guide has it.
Most of the content is as useful for Australian, US, Canadian and other governments as it is for the UK - heck it's useful to anyone seeking to engage people online.
The site also features an awesome collection of examples of online engagement and Government 2.0 initiatives from around the world.
How awesome? See the image to the right, which is a screen capture of the examples page listing every example in the site right now. Yes, it is extremely long, so long that I'm having to write extra words simply to make this blog post long enough to match the image!
Don't get daunted by this however, you can select subsets of the examples, strategies and techniques by keyword, location and topic.
And if you can't find your own online initiative in the site, you can submit it using the Contribution page.
Dang - that image was still longer than my words... so many examples!
