Since it was tacked onto the slasher movie, “Sorority Row,” which opened this weekend, many have been posting the brand new trailer for “New Moon.”

The second installment of the “Twilight” vampire series debuts Nov. 20, natch!

And, actually, while the first film left me in a mild stupor–BoomTown is so not the demographic for the film–this one looks pretty good because it seems chock full of the Olympic broodiness of Kristen Stewart (who is also filming a biopic about Joan Jett, which completely redeems her in my book).

Here’s one of the many video trailers, one of which already had 2,732 comments on Google (GOOG) video site YouTube since it was posted just yesterday, most of which are text versions of teen girls screaming:

And here are the first two trailers, released earlier this summer:

As BoomTown expected, the popularity of the chaste-yet-lustful vampire movie for screaming teen girls everywhere, “Twilight,” has inspired more online video spoofs than you can shake a braided rope of garlic at.

Rabid fans of Stephenie Meyer’s book series flew into theaters all weekend, adding up to a $70.5 million U.S. box office tally so far.

Thus, we are in for more online videos in praise and in mockery of Edward and Bella than perhaps even Alaska Governor Sarah Palin engendered.

Here’s one of the oh-so-serious “Twilight” trailers, followed by one of the better spoofs–by Evil Iguana Productions–below it:

Of course, a lot of the attention last week was aimed at MySpace, which had only a very peripheral role in the appalling story of a gang of teen harpies from Florida who viciously laid into another and videotaped it.

The unfortunate girl–whom the female wolf pack (to be fair, wolves are a lot more intelligent) was heard accusing incoherently in the video–had apparently posted something on MySpace–owned by News Corp. (NWS), which owns this site–that apparently ignited their rage. Thus, the genius leader of the half-dozen girls planned on posting a video of the beat-down to MySpace and also YouTube (GOOG).

The parents of the beaten girl, who was severely injured in the incident, urged the sites to prevent users from uploading the viral video, even though it was never uploaded by the teens and has been regularly taken off the services when it has been.

(I could not find the video on either service last night, except in snippets as part of news coverage. It is available on Salon here, and can also be embedded, which I decided not to do here.)

Still, the injured girl’s father was quoted in a local newspaper: “As far as I am concerned, MySpace is the anti-Christ for children.”

Actually, the gang of girls get that particular moniker in my estimation. In any case, justice will be meted out, I am sure, and it started with the judge’s order that the defendants not use any social network.

And while it got a lot less attention, don’t miss New York magazine’s riveting story of a Facebook scandal at New York’s tony Horace Mann private school.

In the piece, titled “Testing Horace Mann” by Gabriel Sherman, Facebook is used as a vehicle for disgruntled kids to create obnoxious groups attacking teachers they don’t like in verbally appalling ways and without any apparent recriminations.

Laid out in exquisite detail are how petty school politics, overindulged kids and parents who need their heads examined collided to create the digital equivalent of “Lord of the Flies.”

Here’s the money quote:

These Facebook pages, however, were something different. Kids have always ragged on an unpopular teacher or ridiculed an unfortunate classmate. But sites like Facebook and RateMyTeachers.com are changing the power dynamics of the community in an unpredictable way. It is as if students were standing outside the classroom window, taunting the teacher to her face. Should they be punished? There were, as yet, no rules or codes for how a school should address such issues.”

While it is pretty obvious that it is easy to blame the technology in both these cases, there are bigger societal issues at stake here that nothing MySpace or Facebook can fix with a simple tweak.
