I would be like, "Wow, thanks for the advice and the ringing endorsement." The guy is obviously trying to help Patrick out in multiple ways. The author is trying to make him realize how amazing he is and tell as many people as possible how valuable he is.
Personally, I might be a bit uncomfortable while reading it. But sometime down the road I'd look back on it and be very thankful.
OK, point taken. It might have been more difficult, but it could definitely have been possible to give him a strong endorsement without the rest of the post. Then he could have sent Patrick an email with the rest, indicating that the blog post might be a good reference.
