You have instantly earned much reputation by releasing Volt at the first time; that reputation is much easier to lose as well. People easily gets disappointed, no matter what you have achieved (or think that you can achieved); you should be very careful. Or you can stack much reputation that your mistake or short-sighted action doesn't harm yourself.

[2] Not that I like this form of release. Proprietary languages simply don't work in the modern world.
EDIT: s/open source/free/
You can't call an unreleased language proprietary.
Many current programmers think F/OSS as a norm and proprietary (released or not) as exceptionally shady. Even though some may think proprietary software is acceptable, something being F/OSS is a label with the non-trivial amount of value. Your act can be interpreted as claiming that value without actually being F/OSS, no matter what was your intention.
Without releasing it you're expecting people to put blind faith in you.
My comment was sarcasm by the way.
And sorry for the delay, I was sleeping.
