Have you changed the default gravatar (Globally Recognized Avatar) of your WordPress blog? Sometimes we just are lazy and refuse to think. That makes us look like others.
Trying as much as possible to give our blogs a custom and personal look is what bloggers should consider to do today. It doesn’t feel well to look like every other blog that runs on the same premium or free template as yours.
There are, as a matter of fact many things to do to look different and stand out. One of the things I recommend is change the default wordpress gravatar to something more personal and unique.
