Asking friends, family and colleagues for help is a great start. But, honestly, if you dig around, there are a lot of people out there talking about best practices and social conventions on social media tools. Don't be afraid to ask.
Here are a few good starting places.
I asked Mark S. Luckie, manager of journalism and news at Twitter, where to send you for basics on his favorite social site. He says the various resources on Support/Twitter are very helpful. I also find the official Twitter Blog interesting.
Facebook used to have an official blog, but they now direct us to their Facebook Newsroom. Facebook's Help Center can give you directions for specific problems -- resetting a password or adding a profile photo. Try it. But sometimes the best way to learn a web tool (and all these social media sites are tools), is to practice, try things out. Figure out what works for you and what doesn't. Maybe you'll pave a new path.
