Twitter Link Explorerhas a very simple welcome page, use oAuth to authenticate. That is it. The only other thing it states on the homepage is that it only needs read access to your account to see links your friends post. Which immediately led me to believe they don’t send a tweet out and do not have retweet ability.
Once you authenticate you get a small bar at the top showing the tweet itself and the original shortened link. The rest of the page is the exact page where the link would take you. Very clean and smooth. You could then easily go to the next link using a giant arrow to move along.
This is a great way to browse and see links yet you really don’t get to see the link or where it is taking you. I would love some type of preview to let me know the next link is safe before moving along. Or a way to preview the next one instead of just blindly clicking.
