After asking a few questions on Stack Overflow, I completely lost my ability to answer to comments on my questions yesterday. The only thing I can do is post more questions.
I am fairly new, and I asked a question on Stack Overflow, but was told that I should ask here.
I read the FAQ but it doesn't help me. I also don't think I broke any rules, so I don't get it. In a comment on my previous post, someone mentioned "karma". What is karma? Is it reputation? He says I need more than 100 karma to answer comments, but the truth is that I was able to answer comments when I had less than 100 reputation points (assuming karma == stack rep points) and now suddenly I cannot.
What am I doing wrong, and how can I fix it?
As an additional question, I have realized that some of my questions are being closed and downvoted by people that don't even take the time to read them. They just read the title and assumed that I am a jerk (I don't think my titles are offensive by any means, but then again I am not a master in expressing my ideas as you can probably see by this wall of text).
What can I do to stop them? I have the feeling there will always be someone that doesn't like me, and if that person has more power, I will always be harmed by it, even if I did nothing wrong.
Last but not least, I always start my posts as polite as possible by typing "Hello gentleman" or something similar, but Stack Overflow always removes that. Why am I not allowed to be polite?
