I care about URLs. I have spent time ensuring the URLs for this site are clean, concise, uniform, readable, and easily sharable. I subscribe to the idea that cool URIs don’t change and that URLs are UI. Even while I recognize that the “appification” of the web has minimized the importance of URLs, and I expect URLs to become increasingly niche as computer interfaces become conversational, the URL remains the defining feature of “the web” as we know it today, and I believe we should design URLs to embolden visitors with confidence.
