Thanks for writing this up. It amazes me that companies (particularly startups) spend so much to recruit great people and then let them sink or swim. The first 30/60/90 days for a new hire are critical to their short and long term success at your company. More Founders should understand this.
Many good ideas, ideas that one might eventually find mimicked in other orgs (just sent the URL to my partners...).
The sad thing is that much bigger companies often don't get this right.
