This site has some handy tips for Drupal web developers.  Some of them seem to be a bit outdated, such as the one for a WYSIWIG editor, since there are 2 standards for that (ckeditor/imce and one I can't remember.  We primarily use ckeditor for no particular reason.)  Others are primarily for speed management.
