I'm not planning on taking investment at this time.
I think this is a really good deal, though. The $10,000 is gravy, and not worth nearly as much as getting to pick Dave McClure's brain regarding distribution. (Metrics, design, product, too, but if you had to pick one of them, distribution is a strong choice.)
It just doesn't mesh well with the trajectory I'm shooting for at the moment. If that changes, I will start working on the first investment pitch delivered in rAnS0m n0tE.
My experiences with YC and TS companies indicate that the most valuable aspect of the programs are the introductions and knowledge sharing amongst classes.
Given that the dilution is minimal, I'd strongly encourage you to apply - you'll get $10K of value by getting accurate quick feedback from the other members of the batch on the question "is there a better way to do [x]?" I don't think the $10K obligates you to go out and get any additional funding, and Twilio will be a net positive in terms of PR and links.
