Adding a photo to your account can go a long way towards increasing trust among your readers because really, who doesn't like to see a proper picture of the author? Transparency works when people can remember you better as you'll be much easier for them to relate to.

The cool thing about using Gravatar is that not only will your picture appear on WordPress whenever you comment, it will actually also appear on other websites too because Gravatar has partnered with many websites on the web.

Show your sexy picture to teh world!
