> All that said, don't hesitate to keep in touch. Your project has a lot of merit, and sounds like it will be real winner with the right team behind it. I'm looking to hearing about your eventual launch!
Anyone who's frequently dealt with proposals and rejections knows that this is a meaningless gesture. E.g. lesser VCs use this "keep in touch" line all the time. After hearing the 10th person say it, who you know couldn't care less about your project, it starts to feel extremely fake.
You learn if it is a meaningless gesture by how the follow up goes down, not based on "all the other people who said it were full of crap." This is a problem genuine people run into. The only antidote is to say what you mean and mean what you say, not avoid saying what you mean for fear that people who got burned in the past will hear a polite fuck off.
