I am not sure why a lack of sources or the fact this website expresses the views of particular Rabbi should be an issue. After all, the Rambam didn't quote sources nor did the Kitzur Shulchan Aruch. Both books were meant to be clear and concise guides which don't require the reader to follow the full halachic process. With any halachic work one needs to know who the author is and if their rulings are reliable and acceptable to you and your community. That's true of a book or when asking a Rabbi a question directly.
