A kind fellow, Joshua Goodwin, has informed me that my link-post items did not include a permalink back to my site when viewed in an RSS reader. The titles of the link-post items will continue to link to the external sites referenced; however, I have added a permalink to the end of link-post items in the RSS feed so you can now click the infinity glyph (∞), and it will link you back to the post on Indigo Spot.
Thank you for the suggestion, Joshua.
Be well.
