Yennifer,
I get what you are saying. One wants to have some sort of positive acknowledgment that what we say (post) has some sort of value and is recognized by others. Personally, I like it when somebody says "good point" - or even "sorry, I don't agree" because it makes me feel like I have had some sort of impact and cant help but feel a little disappointed when my comment or post passes unnoticed.
That said - and remember, I am a still a relative new comer here - I am starting to figure out how Susan's works. There is an incredible flow of new posts every day on so many many many different topics. Even though I try to get into Susan's every day there is just no way I can ever hope to read, let alone respond, to all the new posts. So each of my own posts enter this noisy river of commentary, sometimes to be noticed but often not. But every post and comment goes into a vast pool of shared experiences, opinions and knowledge - there for your taking, at your leisure and when you need it. I am learning to treat Susan's as a valuable source of knowledge and a way to connect with a community that doesnt really exist in the New Hampshire country side. I may be just one of many in a crowd but I feel less alone and I am getting smarter about many topics!
So, please know, your posts do have value to the community and I personally appreciate that you have taken the time to make them. I hope you decide to stay!
