Yeah. I did some Internet sleuthing and found a potential contact for the Salesforce Open Source Program Office and reached out. We'll see if they get back.
So, after contacting Bob Wise via Linked In (as he graciously invited readers of his blog post to do!), I constructed a concise but hopefully persuasive email about why they might want to sponsor me, to eventually successfully get this form response...
> Thank you for reaching out to ospo-heroku-credits@salesforce.com in reference to requesting Heroku Credits for qualified and selected Open Source Programs.
> We are in the process of finalizing the selection criteria and will contact you when we are ready to start the process; we anticipate this as no later than Dreamforce.
> In the meantime, should you have any questions or feedback, please do not hesitate to contact us via the above email address.
["above email address" not sure what it means, the email was sent from a personal email address, which i won't share on HN]
So... not yet, in fact!
I had to look up what/when is "Dreamforce", looks like Sep 20-22.
I was just about to write an email too, I guess I won't... yet?
