On Friday, we tell you about a student who was so upset about an ingredient in Gatorade that she got an online petition started.  Her goal: to get Gatorade to drop the ingredient and change its formula.

The ingredient is considered safe by the U.S. government, but Gatorade said it was getting rid of it anyway "because we know that some consumers have a negative perception" of it.

All this got us thinking:  Have you ever taken to social media to try to get something changed?  And would you call social media are a good way to cause change - or do you think this was just a rare incident?

Thursday's show will bring you my interview with the Boys and Girls Clubs National Youth of the Year.  Her name is Trei Dudley, and she brings up several issues that a recent survey said were most important to teenagers:

• Not being able to find money for college
• Not being able to find a job after high school
• Youth violence
• Risky behaviors, like drinking or drug abuse.

Are these the top issues for you and your friends?  Or is there something else you'd add to this list?

Tuesday's show has a pair of stories about people standing up for others.  We wanted to hear whether you have any stories of your own about that - whether you did it yourself or you saw someone else show that kind of character.

An official from Monday's presidential inauguration told CNN that Beyoncé didn't sing the national anthem live.  She apparently lip-synced her performance over a recording she made before the event.

It's not unusual.  Others have performed to pre-recorded music in previous inaugurations, and most inauguration singers have a pre-recorded backup.  But Monday's other performers did sing live, and critics are saying Beyoncé should have, too.

After seeing the clip in Thursday's show, tell us your opinion.

A debate has been going on for years about whether violent movies and video games contribute to violent behavior.  On Wednesday, we talk about a Florida teacher who believes they do.  So she put some of her own money into a sort of buyback program:  Students who bring in games and DVDs that are considered violent get some of their money back, and the materials are destroyed.

We'd like to know what you think - both of the teacher's program and whether there's a connection between violent media and violent behavior.

Following the swearing-in, the ceremony and the speech, the second term in office has officially begun for President Obama.  Some of the challenges of his first term remain, and some of the issues the president is promising to address include immigration, the economy, gun control, and the implementation of his health care reform plan.

What are your expectations for President Obama's second term in office?

After he reportedly admitted to Oprah Winfrey that he used performance-enhancing drugs, cyclist Lance Armstrong is taking a beating by the public.  Some of his former fans feel misled at best - furious at worst.  Critics are calling him everything from a loser to a liar.  He does have his defenders, many of whom are pointing to his Livestrong Foundation and its work to raise money for cancer research.  But by and large in the court of public opinion, his reputation is seeing its worst days.

Do you think the public will ever forgive Armstrong?  And do you think it should?

It's not the first year in baseball history when no one was elected to the Hall of Fame.  But what is unique this time around is that some of the players who were eligible have also been accused of having used performance-enhancing drugs.  And that could be the reason why they didn't get enough votes this time around.

How do you feel about the way this was handled?  Do you think accused players should be voted in anyway, that they should not have the chance, or that there's some other way to address the issue?
