John Motzi has developed an Excel X-DNA Inheritance Chart that includes only the ancestors who may have contributed to the X chromosome of a person. I have made this chart available on my website with John's permission.
The Excel file can be accessed directly at http://debbiewayne.com/presentations/dna/MotziJohn_Xinheritance_Ancestry_Chart.xlsx. There is also a link available from my QuickRef Links section at http://debbiewayne.com/pubs.php#quickref once you scroll down to the section with links to "Charts for X-DNA analysis by others." You can find John's email address there also if you wish to contact him about the chart.
Because the names of ancestors who could not have contributed to the X chromosome are eliminated, this may make more sense to some of us and make it easier to find common ancestors on the X lines. While my versions of the charts make sense to me, some of you may prefer John's version of the charts or the ones created by others that are also linked in my Quickref section.
All of us think a little differently and the same tool is not best for all. Try this out and see if it works better for you.

Educating Ourselves and Protecting Our Right to Access DNA Data
A prestigious journal has an interesting article on access by individuals to his or her own genomic data. It may help fight the recent rash of news articles generating fear of DNA testing due to companies using our data for research.
Barbara J. Evans, "HIPAA’s Individual Right of Access to Genomic Data: Reconciling Safety and Civil Rights," The American Journal of Human Genetics, Volume 102, Issue 1, 5-10; DOI: http://dx.doi.org/10.1016/j.ajhg.2017.12.004.
While the focus is on US laws and organizations, many of the general statements apply worldwide. Articles like this emphasize the importance of educating ourselves about the interpretation and meaning of DNA markers and our genes. We need to fight the perception that most of us will "make bad decisions that harm both [ourselves] and society" if we have access to our DNA data.
DNA education through teaching and writing has been my main focus in recent years. So many social media users seem to use posts as their main learning tool nowadays. It would be great if those answering questions included pointers to reputable resources where the person can learn more. Education is key to eliminating the perception that we are all dummies when it comes to DNA. Links to genetic genealogy articles and educational opportunities can be found here on my DNA bibliography which is updated as I learn of new resources.
Some key statements from the Evans article:

Some key statements from the Evans article:
Although there are a range of bioethical perspectives on this question, there is a fairly broad consensus within the bioethics community that laypeople can be harmed by access to subclinical-quality genomic data.
...
A large cast of third parties potentially has access to your whole genome, while ethicists debate whether it is “information” you should have.
...
Like the right to vote, access to one’s own genomic data is a foundational civil right that empowers people to protect all their other civil rights, and HIPAA displaced states’ power to interfere with it.
