Leaders Without Borders

Sitting here with a group of novice bloggers doing their first ever post!
Today I am attending the Yorkshire Leadership Conference - Leaders Without Borders. Key speakers included Mary Creagh, MP for Wakefield; Jeanie Bergin - a creativity expert; management guru David Firth; and the always excellent Ian McMillan, poet and entertainer.
I was doing two gigs on social media. Basically a morning and afternoon workshop on social media and blogging. They were lovely people attending but I remain amazed how ignorant many people are about blogs, podcasts, etc.
It's interesting to watch their reaction as the scales drop from their eyes and they realise the potential for blogs and other social media tools in their everyday life. Many were particularly interested in corporate blogs and using social media as a means of communicating with their staff.
My main concern is that by the time most British companies and organisations have created a blog the internet will have moved on to the next big thing - Twitter perhaps.
Any thoughts?
