Yes,  Reddit is good for questions:

• Ask subreddits, which frequently overlap with advise subreddits, allow users to ask questions. r/AskReddit is a very popular destination with 26 million members — but only for open-ended questions.
• Reddit users routinely express questions and seek help on the site. There are entire subreddits dedicated to the practise.
• Overall, with with caution, Reddit can still be a terrific site to ask burning questions, seek help, or gain insight into people's lives all around the world.
