Quote: "Where's that shortend [sic] link sending you?"
Where's that what? Why do you expect people to trust your code when they can't trust your prose? Prose is way easier than code, but apparently not easy enough.
Also, on the topic of prose, why not call it "resolve link"? That's easier to say and more descriptive of the app's purpose.
This is a useful service.
This is a weekend project because I am in the security industry and got sick of being terrified of every shortened link I come across. The Chrome extension will automatically intercept any request to a shortened link and attempt to expand it for further inspection. I also included a link to Google's Safebrowsing service to dig deeper. I'm not very UX savvy so be easy on me.
