I came across this question where two new users had answered and both of them got downvoted.
Now I get why not everyone comments on their votes but I really think if you are dealing with rep 1 users who are making an effort, it is counter productive and may lead to these users felling disgruntled and unwelcome.
A simple comment to explain and linking the help section would go a long way to help these users contribute quality posts.
Of course, this is my opinion and I can't tell anyone to do anything but these users are the 10k users of tomorrow and we should help them, rather than punish them, very few of us would be here now if we were not offerd feedback on our early posts..
This is just my 2 cents.
