Welcome to the new world of press releases: earlier this morning, CNN anchor Rick Sanchez Tweeted out the news that he would be anchoring a new CNN show, Rick’s List.

“Hey guys, new CNN show beginning Jan 18th, weekdays 3-5pm ET. “Rick’s List”- Who will make the list?” reads the tweet, which was picked up by CNN PR’s Twitter account. Could Twitter play a starring role in the much-tweeted about show?

Have Twitter lists been deleted? Compulsive Twitterers may notice that lists, which were just rolled out last month, mysteriously disappeared from twitter.com’s interface earlier today. Twitter lists got mixed reviews when they were unveiled. Did Twitter gave them the axe after such a short time? It doesn’t sound like it:

When Twitter decided to slowly roll out a new, official retweeting feature, people waited in anticipation. When they let their users know what it might look like, people debated whether that was the right way to deploy it. When it actually became available, people almost universally disliked it.

In the wake of the tragic shootings in Fort Hood, millions of Americans scrambled to follow what was going on — and encountered misinformation and rumors at every corner, including TV, blogs, and Twitter. Could Twitter’s new list feature give news consumers better information when stories like this break?

I use Twitter a lot, but I was not among the very first to see the new Lists feature. I can now, though. And what I find much more interesting than actually using the feature myself is the fact that I woke up this morning to find that I was on dozens of other people’s [...]

Yesterday morning, I was up early with big plans for knocking out a few Twitter Lists, boom boom boom. Ha. As if. I could NOT believe how what a time-waster it was — not only do you have to add everyone one by one, but you can’t even type a name in quickly – you have to type in the name in the search box, search, then click on a drop-down menu to select the applicable list. Really? How about just go through your list and CLICK A BOX? But no, multi-adds aren’t possible and won’t be for a while.

After weeks of teases, Twitter has just rolled out its Lists feature to the bulk of its users. So what does this mean for you, Mr. or Mrs. Average Twitter User? What does it mean for the web? What are these things, anyway? Allow us to answer these suddenly popular questions.
