Calling for ideas!!! Why newcomers fail to engage on Twitter.

What is it that makes Twitter so hard to get started with?  Why is it that so many newcomers fail to engage?  We all have friends that have created profiles and just stopped there.  I am shooting a second round of free one minute videos at the end of this week and I would love your ideas.  What do new Twitter users have the hardest time figuring out?   Here are a few ideas for 1 minute videos that I think would be helpful:

-How to survive the first 24 hours on Twitter (following and engaging in your first conversations)

-How to gain targeted followers in your industry

-How to find interesting conversations/people to follow

Any other ideas?
