Assembling a social media guide, what are the most frequent questions you have regarding social media?

My team is working on a on guide to answer the top 20 commonly asked
questions regarding social media, along with some more niche focus
guides. I would love to get some input from the community and any good
links to similar resources.


Do you find that professionals are more likely to ask about blogging or more specific sites like Linkedin?

What is RSS?

etc, etc.

Any ideas and commentary welcome.
