Redscout and PSFK are running a two-month series of videos dissecting account planning. Here's the first video. It's short (which is good) and raises some interesting points.

For me, the most interesting elements are:
1. Communicating value
People value the tangible output more than the thinking that led to it.

2. Involvement in the ‘doing’
If you're involved in an idea, why wouldn't you be involved in carrying it out? This is especially relevant given that on the modern web there is no 'end' because content endures and conversations continue. Iterative planning based on ongoing insight is what's required.

3. Strategic vs. tactical
What should a planner's focus be?

4. Not being an a*se
We don't know everything and others know lots of stuff too.
