Yes, yes and yes.
I hope you have a bit of time to read this as I am about to summarise a 5/6 year tale. One of the main forums for discussing Astronomy on the Net is
news://sci.astro, a usenet group that goes back to the founding of the Net. That group has always attracted it's fair share of nuts, loons and kooks. Some of the most celebrated usenet kooks have graced it's shores. Plus some of it's most celebrated posters have become primary information sources on the Net. For example, <a href="http://www.badastronomy.com">Phil Plait, the Bad Astronomer</a> and <a href="http://www.crank.net">Eric Max Francis</a> to name two off the top of my head. John Baez and Ned Wright come to mind as well. Sci.astro has a web gateway on<a href="http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&group=sci.astro">on groups.google.com</a> with a complete 20 year archive.
Back in about 1996 a new kook appeared. She was <a href="http://www.zetatalk.com">Nancy Leider</a> who claimed to be in telepathic communication with the Zeta Reticulans. Nancy claims that the Zeta's claim there is a Planet-X in the Solar System. This Planet-X is based on Sitchin's and Velikovsky's 'work' but adds in some new age mysticism about density changes, pole shifts and other dreck.
Nancy spammed sci.astro with hundreds of messages a week for long enough. When Comet Hale-Bopp arrived she claimed it was not a comet but a ruse by NASA to deter observations of Planet-X. After the heaven's gate suicides occurred nancy went very, vrey quite until last year. Now she is claiming her Planet-X is arriving in May 2003 and will reign death and destruction onto us all. Read her web site in depth to see what I mean.
Nancy also set up a not-for-profit called <a href="http://www.zetatalk.com/thub.htm">Troubled Times</a>. She runs a Yahoo club complete with weekly IRC chats to talk to the faithful. Over the years Nancy has apparently gained some followers who help run Troubled Times and act as senior management for her. Search the sci.astro archive for JosX, amongst others. Jos has since recanted after a spat with Nancy.
Nancy has also recently appeared on the Art Bell Coast-to-Coast show in the US and since then many, many people seem to be asking about this matter. Nancy is sufficiently convincing that people appear to be listening to her.
But this get's complicated. One of her followers was a guy called <a href="http://www.planetxvideo.com/">Mark Hazlewood</a>. Mark wrote a book, got it published and appeared on Art Bell last year, before Nancy got the publicity. This led to Nancy having a hissy fit and publishing a public denouncement of Mark Hazlewood on her web site and on Usenet.
So, the main proponent of this idea is Nancy Leider on
http://www.zetatalk.com and Mark Hazlewood more recently.
Sitchin recently posted a public denial that Planet-X is due next year. Even Richard Hoagland denounces this. A professional Astronomer has put together a superb debunking of the claims on a web site. Wishing to remain anonymous he calls himself I M Open Minded,
http://www.geocities.com/openmindxx. A detailed debunking can also be read on sci.astro if you read the archives searching for 'Nancy Leider' planet-x'.
As you can tell I have following this for some years. Everytime I hear "planet X" I now think of Zetatalk and not Sitchin.
