I don't. With all the trickery and phishing going on these days, I don't click on anything unless I am confident that I know where that link is going to take me.Everyone prefer short and clean URL.
URL shortener especially helps in twitter post because twitter post uses a limited character if we are sharing a full URL it may be difficult to share at some point. So we use URL shorter to share a link.
