Day after day when using Arqade, I see questions (poorly worded, formatted, whatever the case may be) from users who had just created the account to ask the question.
Almost every time the question never gets answered. Just look at the newest questions now. People with 1 rep who made an account today, asked a question, commented on that question, and will likely never return to the site to select an answer.
I'm referring to questions that have well articulated and well researched answers that the user who asks the question comments on, saying it was helpful, then never actually selecting an answer.
With the way reputation locks several features from new users (chat, edits, comments, etc.) I would think that not earning valuable rep from answering questions would be off-putting to new users who are actually trying to make contributions and go somewhere in the community.
What can be done about this as a whole?
Edit: I am not referring to the user never returning, I am referring to the impact it has on other users who invest time and resources into finding an answer only to have their efforts wasted.
