Is Feedback Important?

I'm really a statistics junkie. Though I thought my "stats" class in college was sort of a drag, I'm very dedicated to checking my on-line statistics every day on Google Analytics, checking my Ebay comments, checking any Etsy comments, checking my e-mails, reading blog comments (I don't miss any comments--they all get read) and seeing if there are any more followers, etc. Each follower is very important to my on my blog--I'm extremely thankful, not to mention honored, for each and every one of you who care at all about what I have to say. Every heart is appreciated on Etsy. Every comment on Ebay sales is read. When I sell something on Ebay or Etsy or Lollishops, getting a response...a communication of any sort by the purchaser...is very important. I can learn a lot from feedback. Does anyone else crave feedback? I feel that if someone DOESN'T respond, that they didn't like what I sent or there's a problem, and they don't want to tell me. I'm really trying to make sure that I communicate with buyers and sellers of items on line, particularly those "little shops" out there where people take the effort and time to create what they sell. Perhaps feedback fills in the gap that is missing in on-line sales--of not physically going into a shop, seeing the shop owner, and communicating with him/her through body language or verbally about the shop and the items in it. To all who have commented on the things I have sold them--THANK YOU! I appreciate the time you take to do so. I'd also like to encourage those who don't give feedback to little shop owners like myself, to do so. The little bit of time you take to give feedback is more important that you think--and appreciated.
