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.
