I will not repost the articles but will offer links and some quotes from them. They are relatively well-written. I do not know if non-Witchvox people can post or not. But they may be of use for background explanations and an insight to what may be referred to as the "magical" crowd.
A Numerologist's Look at 2011

"We are about to begin a new year. 2011 may be one of the most eventful years you will ever experience. Legends have spoken of this time as special. The Mayans, Hopi, Chinese I Ching and the Bible tell similar stories. It is a time of great change. Scientific information is pouring in that seems to confirm many of the old predictions. Let us take a Numerological and symbolic look at the doorway into the New Year. "
2012: The Logical Approach
http://www.witchvox.com/va/dt_va.html?a=usga&c=words&id=14190
"I suppose I’m a little intense about this because the whole 2012 thing keeps dropping into my lap like a flaming meteor from hell. A little background: I do research in the field of geophysics aside from my regular job as a journalist. I’ve been invited to speak at conferences about earthquake precursors alongside scientists from respected universities and institutions like NASA, so I have some perspective when it comes to large-scale disasters (the earthquakes, not the conferences) . When people find that out, I get drawn into some interesting conversations. 2012 is creeping into them more frequently."
“Oh, you study earthquakes. You’re going to be a lot busier in the next couple of years!” Then it begins: they either fix me with a sly gaze that indicates they’re going to let me in on some grand conspiracy, or with the glaring look that tells me they’re going to pronounce some horrible but undeniable truth. The latter folk would have made wonderful desert prophets a couple thousand years ago. They’ve practiced that glaring look quite a bit.
2012: Why It's Not the End

A near miss with a large, previously unknown planet will cause untold mayhem on Earth. An unimaginably powerful solar flare will slam into the planet, and over the course of a day, Florida will become the new North Pole either by the crust shifting or by the planet's iron inner core flipping over. The Earth will collide with a brown dwarf called Nibiru, smashing our poor planet to bits. Generally, the end of the world as we know it. Sounds pretty bad doesn't it? According to a plethora of TV shows, documentaries, books, websites, and a big budget movie… that's exactly what awaits mankind on December 21, 2012.
Scared yet?
If you are, you're not alone. A lot of people are at least mildly concerned about this 2012 monster. Some of the theories sound remarkably scientific and convincing, not to mention the clout the ancient Maya prophecy brings. Surely, this is something we should be concerned about, right?
The very short answer is, No. There's not a reason to worry about December 2012 any more than you'd worry about December '11 or '13. There's hardly a shred of truth in any of the 2012 theories on the market. Though we may be spiritual beings, we were gifted with the ability to discern between fact and fabrication. And 2012 does not pass intact through the trials of a discerning mind.
