I get the envy, it is nice being able to fund a language. I feel vaguely guilty like I was scratching my own itch, because that's exactly what was going on. I'll feel less guilty if someone else says "hey, cool, looks like C" and plays with it.
I think if I did it all over again I'd open source it sooner.
I understand why you did it with your VCS, but with a scripting language? I would have made it open source sooner, too. Then again, as the business owner, there are always other angles that need to be considered.
The other aspect was that I wanted the language design to settle down before open sourcing it. I wasn't interested in a "design by internet" language, my experience is that stuff that comes out of one mind tends to hang together better. I probably waited longer than I needed to :)
