I always reply with a thank you.
However not always get a reply to my e-mails when someone asks for an opinion.
And even once I had this happen:
got an e-mail from a guy asking about a certain speaker and I replied with a very thorough, nice and detailed e-mail reflecting my thoughts on the speakers in question.
Got nothing back from the original requestor, but got an insulting e-mail from his buddy, who disagreed with me displaying a fair amount of rage.
Can't figure this one out, but what are you going to do?
