I am incredibly sad to report that the beloved Bill Atchison, known in the SEO community as IncrediBILL, has passed away. He has been sick for some time now and has now moved on. He was so well loved and respected the the SEO and webmaster community, that everyone who has ever known him in-person or online is devastated.

He has contributed so much the community, his WebmasterWorld profile shows that he had almost 15,000 posts there. He joined the forums back in January 24, 2005. On Twitter he posted over 18,000 times, we covered his contributions on this site countless times and he has been so giving of his time over the years, he was a true inspiration.

His bio at WebmasterWorld reads:
