Can't you find interns to help you with stability? Even I would help for free just to get some experience with a very large site.
Each time we've had a new programmer come on board, it takes about 6 months for them to become familiar enough with the code to make a solid contribution. In the mean time, it actually slows us down a bit. That was the main reason we didn't seek programming interns this summer -- it's a great thought, but would probably take too long to ramp them up.
First of all, thanks for your hard work on reddit. I'm myself quite addicted to some interesting subreddits for about 6 months.
I would like to answer on your issue with the 6 months problem that interns 'would have' if you pick one. If I'm right, you released a virtual machine with reddit installed, last month, on a blog post. I see no reason for _any_ intern for not being able to contribute to reddit from day 1.
Seriously, /r/programming and /r/coding are great, and I'm 110% sure you can find an intern which would know perfectly how reddit works (code related) and who would be very kind to help out.
This virtual machine already setup was a great idea, why not using it to your own goal ?
