Was It Viewed? is a simple web app that creates trackable links to you can find out if any URL has been viewed. If you sent in an online resume, asked someone to check out a video, or want to know if a friend downloaded a file, it will let you create a simple, trackable link that lets you know when someone is checking it out.It doesn't matter what the link is — you just enter it into the the webapp's form, add your email address (for notification purposes), and any notes you want to add. This will provide you with a long and short URL that you can send to anybody. The downside is that the URL identifies itself as a Was It Viewed? link so the person is going to know their activity is being tracked. (You could avoid that issue by using a URL shortener and tracking through that instead.)
This is definitely a specialised tool, but it's a good way to figure out if what you sent was ignored or not — something that can definitely come in handy during application processes.
