I don't think the year 2018 really matters, but many folks need some way to shorten those extremely long URLs. Twitter users are very familiar with URL shorteners since it happens automatically for each tweet. In short (pun intended), a URL shortener takes a long URL and converts it to a smaller one that you share with anyone and that gets redirected to the original longer URL. Tech Viral listed a few of its favorite URL shorteners for 2018.
Frankly, I'm not a big fan of URL shorteners and an even lesser fan of QR codes. The main problem with shortened URLs is that you don't really know where you will be redirected to if you click on it. What a great tool for the distribution of malware. There is a solution if you want to take some extra steps. Services exist that will expose the original long URL before you are redirected. Here's a list of some of those URL expanders.
