Yes, definitely. Which is why I made my earlier suggestion of having the entire production team mentioned at the end of the last audio file.
Just thinking more broadly about why people undertake the work they do:
2) non financial rewards
3) job satisfaction
We currently draw people mainly from part 3), which is fine, but I think more people may be motivated to do work here (or to continue to work here) if we can increase 2). 1) is out - obviously we can't increase their salaries! We also can't use a lot of 2) that workplaces do - we can't give people more office plants, a certificate to hang on their wall, references for their landlord or an educational trip to the Bahamas. We also don't want to fall into the trap of competitive acknowledgement like an "employee of the month" award. A non-competitive acknowledgement which is open to everyone who does the work, that's the ticket! We already have the "thank a reader" facility, and relatively recently added the DPL to the catalogue page, which I really like as I do quite a bit of PLing. I also like the recent innovation of the monthly "Libriversaries" post.
The readers are allowed (not compelled) to add their own voice credit into every file they read, including advertising their blog/website if they wish. It would be easy, and wouldn't cost anything, to give editors, BCs and MCs the same right to a voice credit that readers already have. I suspect most wouldn't do it - IMHO it is more hassle than fun to record a 2 second voice credit, but as a soloist I'd be happy to give a voice credit to the MC, if they wanted that.
I think it is narrowing the field of volunteers unnecessarily to insist that everyone who does work here must be motivated solely by 3) job satisfaction. Not only that, but to insist that those who want to volunteer to BC must also do all their own PLing and editing. When it comes to unpaid work, spread it out as much as possible and engage as many people as possible! That is (IMO) the way to prevent burnout.
I work in an official capacity in two other volunteer organisations, in addition to volunteering here, so I'm fairly familiar with this issue. As a volunteer organisation there are only a few avenues for giving people credit/pats on the back. However, there is no limit to the acknowledgement and thanks we can give. Just because one person has wished you a "Happy Birthday" doesn't stop others from saying the same, or even sending a card!
Non-financial rewards - bring it on! If one of the cover makers wanted to design a "Librivox certificate" which could be emailed to people after achieving 25 recorded sections, or 50, or 100 or 1000 I'd be in favour of that too! Heck, put a gold medal and a star on it! It costs nothing and if it makes people happy, why not?
