respond to my discussion has been deleted.....

Huh?...what was deleted,the discussion or the response?whose stars went down,yours or your friend's?...
If your friend just wrote: 'nice discussion' as a response,then mylot might have deleted it because you know those kind of one word/one phrase responses are not considered quality ones,if everyone would just reply with a word or two, mylot would be nothing... it does happen sometimes to write less in comments, but when it's about a response then I agree in deleting the short ones,no matter how it affects the person,we must learn about what this site is trying to do,and respect that..and if we don't like it then nobody keeps us here by force...
You know that there are 2 ways of writing in a discussion: responding to it, clicking on the 'respond to this discussion' button, from under the topic, or commenting,by pushing the 'comment' button from anywhere in the discussion.If we just wanna write a simple commentary, then we should press the comment button and not the respond one..in this way we prevent such problems.. I know comments don't earn us money, only responses do...so when it comes to earning, we should give our best or do nothing,instead of just writing words here and there.
Maybe some mistakes are too highly punished but I think it's preventing discussions to become an endless list of one word questions and answers,so it's all for the best
