Major New Twitter Feature: Create Multiple Custom Timelines

Now you can organize tweets into differentiated timeline buckets based on, say, an event or a topic. You name the timeline, and choose the tweets you want to add to it – by hand or programmatically using the API.

The difference between a custom timeline and a Twitter list is that you can tailor and craft the content to your liking, adding or removing tweets a la carte.

Each custom timeline is public, has its own page on Twitter.com
