I just noticed in the last couple of days that the sharing platform AddThis has removed “via @addthis” at the end of tweets using their widget. I use AddThis throughout the site. It’s a handy little widget that allows users to share articles through any social bookmarking/sharing site, like Facebook, Twitter, StumbleUpon and Pinterest.
As a website owner, I use it to tweet articles to my Twitter account. I used to manually get rid of the “via @addthis” suffix each time to give me more available characters and to make the tweet cleaner.
