While you are right, you sound like you are trolling
That might sound rude, but if you're going to say that sort of thing is your skill, then at least make that clear in the execution of your own self promotion.
Now, that might feel like approaching troll level statement. But it's simply true. Would you want this person doing your startup's marketing, based on what they've posted here?
Opened this thread excited to begin conversations with potential partners, and instead was greeted with text I'd never put in front of my clients.
Very disappointing!
