Whether a question is sent in an email, posted on a message board, submitted as a comment to a blog post, fired off to a Facebook post, or spoken out loud, try and be as clear as possible.
- pronouns (he, she, they, etc.) if the reference is not clear;
- nameless titles or relationships (doctor, Grandma, Uncle, etc.);
- abbreviations and other shorthand that someone else may not know;
- do not self-create abbreviations;
Your goal of asking a question is to get an answer. If someone cannot understand your question, they may choose to ask for clarification.
Or they may simply bypass your question entirely. Remember that it is the internet and people often move onto the next shiny thing.
