EDIT: I notice you mentioned a newsletter for asking for help:
> To that end, we might use our newsletter as a way to explicitly ask for help. For example, we could include three specific open issues in each newsletter that the public could jump in on.
Something the Coders For Sanders team has found effective is using Slack. I noticed you use Slack as well (from your screenshot). Perhaps 18F could spinup an 18F outreach Slack team, where people with tech skills could join and interact with 18F employees. It closes the feedback loop faster than a mailing list or newsletter.
*I work at 18F.
Other than that, prioritizing what's important and needs to get done in both.
How can I leverage these young minds to get excited?
Do you have hackathons?
Do you have an incubator?
Do you have an open list of problems with grants?
These are the type of things that I think would help. Feel free to email me at jbhatab@gmail.com if you wanna chat more :D.
And our blog, which details many of our projects, is here: https://18f.gsa.gov/blog/
We occasionally hold hackathons but the best way to get involved is through our repos! They can also fork/adapt any of the projects they see there.
To be honest a lot of the tech startup people I interact with have tremendous egos and they need to know the end of the tunnel fulfills that ego, so big money startups is what resonates with them. I'm looking for the marriage of startups and government basically.
I'm just being hyper critical, but I figured raw feedback would help
