When posting, it is important to keep in mind that tone of voice does NOT translate well to writing - and that it is entirely possible (even highly likely) that a response taken as "snippy" was intended as helpful, kind, and maybe even slightly humourous, but that the person writing the response has a different style of communication that the original poster isn't accustomed to, or wasn't looking for. It is also possible that the person writing the response interpreted the original question as "snippy" or "rude" - and so responded in kind ;)
It is a choice to interpret any post as "snippy", or "short", or even "rude", but that does NOT mean that it was intended that way. It's generally easiest on the mood to look at anonymous writings on the internet as being totally impersonal --- and remember that interpretation of the "tone" is our own personal perspective and may be a fair bit off of intention. It is our own choice to interpret something as offensive, or helpful, or not worth noticing --- since an anonymous writer on the internet has no power over us other than the power we give them.
Personally, I love getting responses that are opposing views, or different perspectives, or are downright cantankerous! Those are the answers that shake me out of my complacency or comfortable way of looking at things and actually LEARN something --- and I can admit that you sometimes have to be more than a bit blunt and snippy to get me irritated enough to step out of the comfort zone ;)
The joy of the interwebs - vive la difference!
Sir Terry Pratchett:
"Science is not about building a body of known 'facts'. It is a method for asking awkward questions and subjecting them to a reality-check, thus avoiding the human tendency to believe whatever makes us feel good."
