I am currently one of the administrators of a private team based on Stack Overflow for Teams. Like most of the members of Stack Exchange Q&A communities I have seen the question upvote increased from 5 to 10, including on private communities.
I do not think this is OK, at least for the community I am trying to develop:
the main message for promoting the community is "getting answers to your questions". It is important to emphasize the answers part
based on experience, I would say that, on average, to write a decent question in the community takes about 2-5 times less effort than writing an answer. As a principle, I believe that the reward should approximately be proportional to the effort spent
those who have the knowledge (know-how) and are also willing to spend an effort providing good answers are only a fraction of the entire community. I really want to reward more this effort
[most important] Some of our members has explicitly said that they would like real-life incentives to spend effort in the community. Not exactly the SE spirit, but this is life. Our company already provides some incentives (e.g. vouchers) based on side activities (e.g. write an article for the tech blog, present something at a tech conference) and I am willing to include the platform in this incentives program.
The simplest model to provide incentives is to use the reputation (e.g. highest reputation earned in current month, TOP 3). However, since asking a question is way simpler that answer it, there is a big chance that I fail to reward the bigger effort.
So, please allow Stack Overflow for Teams to specify or use the old question upvote value (5p / upvote).
