It depends how you ask it. This is true of every type of question*, but it is easy to forget about when asking for a book recommendation.
Simply asking "what is the best book to learn algebra from?" is a bad question (high school algebra, or abstract algebra? Also, any answer will be opinion-based, due to the word "best"). Asking "I've finished the book X and really liked the topic Y; is there a standard text I can move on to now?" would be better.
I link hardmath's suggestion in the comments: look at the tag and try to see what would be required before posting. You should look at both good questions and bad questions. For example, if you have enough reputation you can see this question, which is pretty bad and was closed as a duplicate. However, the linked question there is this one, which is excellent.
*Just because there is a group theory tag doesn't mean I can dump all my group theory homework here - I'd have to craft my questions nicely.
