To those Blogger users who are fond of sharing their own blogs/blog posts on Twitter, you might notice that unlike Wordpress (or other websites, for that matter), Blogger links do not show links like the one showed above by default, but instead, they will just show plain links. I don't know about you, but for me, links don't really look good on a Tweet. Not only does it not look good, it also takes up more space than it should.
So this is what your link will look like by default. With the Twitter card showing instead of that link, you could've had a better, more aesthetic appearance for your tweet.
If you're curious on how I change the link to a Twitter Card, feel free to read on.
