Your Gravatar is an image that follows you from site to site appearing beside your name when you do things like comment or post on a blog. Avatars help identify your posts on blogs and web forums, so why not on any site?
A Gravatar is a Globally Recognized Avatar. You upload it and create your profile just once, and then when you participate in any Gravatar-enabled site, your Gravatar image will automatically follow you there.
Gravatar is a free service for site owners, developers, and users. It is automatically included in every WordPress.com account and is run and supported by Automattic.
Firstonweb’s opinion (SEO – wise)
We believe that any means that helps information personalization, must be used. Such is the gravatar, incorporating our image as a personal brand to the information handled on blogs. Therefore we encourage using gravatar as a web marketing technique.
Probably it doesn’t provide an absolute contribution to Search Engine optimization (SEO) but it certainly improves user experience ( User Experience Optimazation – UXO ) and the aggregates the commenter’s recognition, increasing the chances to make the information viral.

Where Will My Gravatar Appear?
For your Gravatar to appear on another site you use, comment on, or interact with, here’s what needs to happen:
The site you’re using needs to support the Gravatar service for loading images. Though many sites and blogs do this, Gravatar isn’t yet in use everywhere. Notable exceptions are services like Facebook, Twitter, and LinkedIn, which don’t yet support Gravatars.
The email address you use for your account on the other site must be one of the email addresses that is registered to your Gravatar account. Gravatar uses your email address to provide your image to other sites. If we don’t have any record of your email address, Gravatar won’t be able to display your image.
Your selected Gravatar must use a rating that’s permitted by the other site. Lots of sites restrict Gravatar images to G or PG ratings only. WordPress.com blogs are set by default to only permit G-rated images. If your Gravatar’s rating is higher than the rating allowed by the site, a default image will appear instead of your chosen Gravatar.
