i agree - there was definitely a bit of deflation at the end when i hit the plug for his services. i'm not saying kareem did anything wrong either, but there's definitely a difference in feel between "this is some cool thing i did that helped me with my job, and i'm sharing it so you can check it out too" and "this is some cool thing i did that is my job, and if you found it cool you can engage my services". it's not that the advice itself becomes suspect in some way, it's more that some subconscious sales resistance kicks in, so you lose the "cool" factor.
