A list of places to post about your startup/launch
No, no no.Post to people who will value your idea and give you valuable feedback.Just trying to get "traffic" is a wasteful and distracting vanity metric. The feedback you get from such traffic will take you further away from building something that really connects with the right audience.(In the case of the list itself, it is worth posting it to those sites, as the audience at those sites is the target audience for the list itself. Which makes it hard to point out why the list is misguided.)
