Long Term

I've just started a group on linkedin: http://www.linkedin.com/groups/Drupal-6-forever-long-term-7460995

Purpose:

For smaller businesses and non-profit organisations, migrating from Drupal 6 to 7 (or 8) would represent a significant investment, quite possibly with little or no tangible benefit. However, Drupal 6 will very soon be unmaintained, meaning no further security updates, bug fixes or enhancements. The same is likely to happen to third party modules.
