"In preparation for the 2009 South by Southwest music festival (March 18-21), NPR Music's spent weeks sampling songs by more than 1,000 of the acts in attendance. Some of the music induced swooning, some of it induced sleepiness, and some of it made us want to pry out our eardrums and swallow them for safe keeping. (We're looking at you, Gaybomb.) Arranged alphabetically by artist, the 100 songs in this ridiculously bountiful — but by no means definitive — mix all passed a simple litmus test, summed up in six simple words: "Yeah, I'd listen to that again."

"It’s clear to anyone who watches a twitterstream that people put out questions to Twitter similar to how they use search engines. But if anecdotal examples aren’t enough, a survey I conducted last week confirms that Twitter is used as a search resource."

"10,000 new followers per day sounds like an astounding number but are all of these followers legitimate?"

"We are witnessing the rise of a social nervous system"

"With Twitter, I feel like I’m interacting with the world–or at least a few million folks who inhabit it. And I kind of like the bustling, fast-moving anything-can-happen feel. Facebook, by contrast, is a quieter, more mundane, more predictable place. Generally speaking, I know who I’ll run into there."

So here’s an unanswered question: Will Facebook ever open up more, in the sense of encouraging looser, more far-flung interaction between members, whether they’ve friended each other or not?

"Billing is the heart of the new business model and the solution. People already buy subscriptions and pay for them through a variety of electronic payment systems such as credit cards. But electronic billing for a subscription to a physical product like a paper is not the billing model needed for digital news delivery. A subscription to an on-line paper must be capable of being shared among the people in a household, simultaneously and on multiple devices. Newspapers need a digital business model whose heart is a digital subscription billing model."

"Like it or not, the wrenching restructuring is going to effect everyone. For all of us — the unemployed and those fortunate enough to still have jobs — it's time to get that Twitter account, time to sign up to Linked-In, time to aggressively hunt for online friends and followers. We are all Scoble now. The world, for better or worse, has been Scobleized."

"Twitter appears to be in the process of rolling out its integrated search feature with a search box and a trends button appearing on some user profiles today. While the feature is not yet available to all users, our guess is that it's very much on the way – and soon."
