Without a Gravatar, you are a faceless being
Imagine what would be your situation if you show up in disguise on your first DATE? Wow, that would be inauspicious to your partner.
Plus, you're likely to undermine the confidence of your first date.
So why would you choose an image of a cat or dog to represent you in blog comments? This is going to be something weird and may manifest the sign that you're not sincere.
Instead, let people see the real YOU.
To do this, go to en.gravatar.com. Gravatar is the short form for Globally Recognized Avatars.
Step 1: Sign up for a Gravatar Account. If you already have a WordPress website, first navigate to the Gravatar website and sign in with the same credentials you used to sign into your WordPress Dashboard.
Step 2: Manage Gravatar by linking the same email and add a photo.
Step 3: Create a Gravatar Profile.
