@swansonphotos is trying to be cheeky but in the world of social media the shortlink is needed as Twitter will automatically create their own shortlink if the URL is too long so either way a shortlink will be created. Better to keep the domain branding then have it lost in some Twitter t.co shortlink.
I too use the shortlink a lot as it allows for posting a shorter link with domain name branding in Twitter and elsewhere. My site has a short domain name so most often there is no need for URL shorteners if the shortlink is used.
The side benefit of using the native shortlink instead of using the longer permalink or someone else’s shortlink is that if I find an error with the title (spelling, corrections) after publishing I can change the title, corresponding permalink and the short link will still work. Without the shortlink the automatically shortened Twitter links are all broken and I have to do a 301 redirect.
