Two entries are collections, not one person's site: personalwebsites.org (a directory put together by @nickgraynews) and bestpersonalwebsite.com (a ranking site). They're tagged collection.
One entry is a name-only mention: @AIBuddyRomano replied with "Derek Sivers (sivers.org)" rather than a full link, so the URL here is built from the name he gave. Tagged name-only.
Two links were posted as http rather than https and are kept exactly as posted; they're tagged http. Everything else is verbatim from the compiled list - no sites added, none dropped, nothing re-worded.
Preview is the default view. "Load all previews" fills every frame a few at a time so the page stays responsive; you can pause it, or load a single frame on its own. Plenty of sites refuse to be framed, so a blank preview means the site blocks embedding, not that it's down.
