Is there any chance you could distinguish between Guide-To-Space links and external links? I do enjoy reading the Guide-To-Space and i love that you include those links. It creates a bit of a wikipedia like atmosphere that encourages learning and further thought. It's just that sometimes i simply want to skim an article to find its source or higher resolution pictures or further reading or whatever, and running the mouse over each link to test is a pretty big hastle. Can I suggest either a dotted underline, or a different colour text for links to the guide?
Thank you, you're my most visited blog. I enjoy your high quality content and love the podcast.
