I wanted to tell you a little bit about some of the exciting changes happening on this site.

First, you’ve probably noticed that photos have been replaced by videos at the top of the posts. Before you do anything else, I hope you’ll sign up for my new channel.

Why videos?

• Some concepts are better explained visually.

• It’s a great way to interact with you (and you get to see what I look like).

• They’re fun.

Why subscribe to my YouTube channel, too? Because you’ll get a preview of tomorrow’s post, plus other bonus material I won’t feature on my site. You definitely don’t want to miss it.

By the way, if you’re a video or TV professional — and even if you aren’t — please feel free to chime in with any advice on how to improve these clips. I’m not trying to be Frontline or 60 Minutes; these are 30-second webisodes that draw on my years of consumer advocacy, TV hosting experience, and my limited Final Cut skills, such as they are.

And one more thing

Many readers have asked about polls and about the posting schedule. Let me address those, too.

Polls. Some readers assume that the electronic surveys tagged to the end of every post must be fair and offer a consensus of readers on a given issue. That’s not true. I don’t want to be the next George Gallup.

I publish polls for two reasons: 1) To offer a quick way of sounding off on an issue, for those who don’t want to leave a comment; and 2) to encourage further discussion. So to the extent that my surveys are provocative and even incendiary, I say: “Guilty as charged.”

Headlines. Look, I love tabloid-style headlines. I confess to it in my FAQ section. This is not the newspaper of record, and someone please shoot me if I ever try to be.

A good headline persuades you want to read the story. If I made you click, then I feel I’ve been successful.

The schedule. Here it is.

Monday – Can This Trip Be Saved? A look at a completely unverified consumer problem, asking readers if I should take it to the next level and mediate it. Note: I don’t always go with the majority vote on the poll, but I promise to listen.

Tuesday – That’s Ridiculous! A consumer case that makes you say, “That’s ridiculous!” Part commentary, part investigative journalism, and 100 percent interesting.

Wednesday – Consumer Q&A An intractable consumer case that I’ve helped resolve. You should expect this to be more thoroughly researched than Monday’s post, but if you’re looking for a legal dictionary, you’re probably reading the wrong site.

Thursday – Case Dismissed! A case that has been denied or where a consumer received less than he or she wanted. Always fascinating (and often frustrating).

Friday – The Travel Troubleshooter Like Wednesday’s Q&A, except on travel.

Saturday – The Weekender. My Washington Post column, a longer think-piece about transportation policy.

Sunday – Security. Also known as my TSA column. Runs Monday on The Huffington Post. If you want to see a lively discussion, tune in today.

I hope you’ll join me for what is sure to be a great final quarter of 2012 and beyond. As always, please send me any comments or feel free to leave one right here in the comments.

Oh, and speaking of comments — we had to migrate back to Disqus 2012 after they removed important features from the old version. Like, the ability to see them on mobile browsers.

I apologize for the inconvenience, but on the “up” side, we now have a terrific team of moderators that are making sure the comments remain civil.
