- Too much "fluff"; his response sounds like a marketer not a builder
- In the opening two answers he basically contradicts his description; "co-authored notebooks" vs. "one author for a given note, and a threaded conversation around it". It's confusing.
- The alternative opening is even worse; I still have no idea what problem your solving. You just gave me a marketing pitch..
- The alternate answer for "Who needs what you’re making?" is better - but immediately begs the question "how are my labels necessarily effective for both myself, and the YC alumni" and "How do you know the YC alumni don't have their own tag system which they apply as they read emails" or even "sounds handy, but how are you overcoming the convenience factor associated with email"
- Any sensible listener will realise that a) and b) are not the only choices (this is a variation on my last bullet point) and be concerned that you are limiting yourself to only those outcomes.
- It also seems risky to pitch such a personal use case on a supposition. The "problem" might already have been effectively resolved for YC's communications.
All in all it reads a lot like a business person pitching to an engineer. One that is attuned to the problems of "gloss", and is looking for disruption and good engineering rather than a glossy pitch. I get that all the time and it is off putting. It strikes me that the key problem is you possibly don't speak the same language as pg.
As with other commentators; even with the revised answers, I'm still not sure what Rocketr is beyond a note taking app with social features.
