I'm sure the intentions were good, but I found the tone of the email to be condescending and obnoxious. e.g.,
We’re better than that, and soon you will be too.
Completely agree - I would be offended by such an email, regardless of my technical knowledge.
Agreed - and worse than that, the list of services seemed mostly like a list of hip ways to waste your time than what I'd expect from the title.
Almost think it would have been more useful just to give him a list of blogs(and twitter users) to keep up with. This will give him a sense of the startup community, and allows him to keep up with services he can look into using under his own will.
