To the Point: Is Your Boss Facebook-phobic?
7. Report, report, report
Share every little bit of progress, and give your boss credit for it! Provide lots of information on what you're learning. The more your boss is part of the journey and congratulated for the progress, the better off you'll be.
Lastly, a word of caution: Don't think you have all the answers. This isn't a crusade; it's a learning experience for everyone. Your boss's recalcitrance might be well-founded. Make sure there is a good case for your initiative, and if it does fail, share and learn from what went wrong. There is no shame in gaining knowledge from mistakes — for you or your boss.
