Twitter is 'a fad.' You follow me?

Citing Nielsen's revelation that a high number of Twitterers soon become quitterers — "Twitter Quitters Post Roadblock to Long-Term Growth"Business Week's Burt Helm had the courage to post this stark headline: "Twitter is a Fad."

Doesn't look like it to me, and I'm not even a Twitterer.

In the meantime, go the Register (U.K.) for Lester Haines's "Pig plague and Twitter: The terrifying truth." The inimitable Haines writes:

Just what role is the internet playing in handling the apocalyptic Black Death 2.0?

The answer, according to CNN, is to spread disinformation, propagate fear and generally convert the unwashed masses into headless chickens drip-fed nonsense by sites such as Twitter.

Haines is referring to CNN's "Swine flu creates controversy on Twitter," in which the cable network (not the social network) notes:

Some observers say Twitter -- a micro-blogging site where users post 140-character messages -- has become a hotbed of unnecessary hype and misinformation about the [swine flu] outbreak, which is thought to have claimed more than 100 lives in Mexico.

"This is a good example of why [Twitter is] headed in that wrong direction, because it's just propagating fear amongst people as opposed to seeking actual solutions or key information," said Brennon Slattery, a contributing writer for PC World. "The swine flu thing came really at the crux of a media revolution."

Twitter's popularity has exploded in recent months, and Slattery said it's a new development that a wide number of people would turn to the site in search of information during an emergency.

Oh, so Twitter is a socially irresponsible thing? That means it will never die. Besides, it's just too easy to use Twitter, so it (or something very much like it) is surely not going away as a way to make instant, superficial contact and try to be super-popular. At the very least, Twitter will outlast daily newspapers, and it's an incredible self-promotional tool.

Meantime, more fun stuff about Twitter from the Register: "Loudmouth workers leaking data through social networking sites."

And this: "Pig plague 2.0: Can't spell 'pandemic' without 'panic.'"

And also this: "Twitter worm author gets security job."

Swine flu's impact on markets? Less scary.

Despite the estimated economic consequences of the current swine flu scare (if it really does become a pandemic), the markets don't necessarily get more than a mild case of the sniffles from flu pandemics, Analyste de Boston notes this morning on Seeking Alpha.

In "Historically, Pandemics Wreak Less Market Havoc Than Feared," Analyste notes:

Looking more closely at the DJIA price movement during the lesser influenza pandemic of 1968-69 and "Swine Flu Scare" of 1976, it's not at all certain that influenza epidemics must move the market negatively.
