Improved Twitter feed curation

Was pleasantly surprised this evening as I logged into Twitter. They now have Lists in Beta - something I've been wanting for some time.

1) I can create lists for subjects that interest me, and move those that I follow into that list (functionally this is akin to creating labels in Gmail). Doing this will create a link on the right of the home-page Twitter feed that I can click and read only those in that list.

2) others can subscribe to this list - which creates a kind of sub-follower rating. Let's say for example that I compile a list of those who tweet about Contemporary Asian art: this would be its own list that interested people could subscribe to (essentially bypassing me and my tweets but reading those that I have aggregated - or perhaps just going to my list to harvest them for one's own list). This is an idea similar to reading filtered blog subscriptions or friends groups in Facebook as well as customized blog-rolls.

3) There are great implications for use for larger or more widely trusted entities whose lists could be very popular to subscribe to. The introduction of this to Twitter's networking capabilities is a tremendous improvement for ease of use and both content and contact searching.

Now, if only YouTube would similarly jump on board with this concept.
