Here is some suggestion to change question formatting.
I have edited some question regarding it. whenever question is asked and it's about to magento 2. some people write question like below format.
"Magento 2 - question"
"Magento2 : question"
"Magento 2 : question"
"Magento2 | question"
"Magento 2 | question"
They always add new symbols so in my personal opinion why we are giving them to add deliminator for question. we can set plain text in question or we can give them suggestion text like "Magento 2 question" so it would be go in proper way for next all questions.
