What is the reason for a shorter link? Does it save money, or is it low carbon emissions? I think I missed the point of it.
not really. the only one I use is when I upload something to OneDrive that I want to share. I then am given the option to shorten the URL. but beside that and even at that, I really don't see the use in them.
I dont like to store things in the cloud but i do have an account in MediaFire to share/store random files but i still rarely use it. Probably just a couple times every year and MediaFire works great.
FWIW, I've run across some not-immediately-obvious redirects through shortening/tracking links. There are some lists of these services around the net. If you have the right blocking capability and are so inclined, you can set up some defensive filters.
