I agree with Deloris. Use them as a starting point for further research but don't use them as a "source" as many contain incorrect information. Once you verify the info contained in the Family Data Collection hint your're researching, or find that it is incorrect, it is nice to go back to it and post the information or verifiable sources you have discovered in the comment section for that hint. Hopefull those that then use the hint in the future will actually read your comment before just linking it to their family tree. My experience in doing this suggests that most won't do that and just carry foreward with the base data but at least your comments will continue for others to read if they choose.
