Quick note for those discouraged over comments of people leaving, and/or low ratings... Just keep in mind that those mean people think you are important enough to actively put effort into interacting with. Someone telling you they are not reading anymore could mean any number of things, but it always means they put effort into interacting with you instead of just ignoring you, so in some way or another, you are important to them for a while at least. Likewise, someone going out of their way to leave a low rating (valid or not) is going out of their way to do so, with the 'hostile' ones thinking you are important enough for them to try to drag down.
So long as you enjoy what you are working on, just treat minimum ratings and 'I am leaving' comments as highly vocal fans that are not very nice.
Now if only I could convince myself to get enough of my own stuff written and good enough quality to allow myself to share and get people to hate me too... lol
