I love the ability to be able to use one profile, including photo if I choose, across many platforms, including but not limited to my Wordpress account, Reddit, and many others, even my YouTube account which, to my dismay, was taken over by Google.
Integrating Gravatar with my Wordpress account has been a struggle. I've been having trouble with it for months and have just about given up on the idea. I'm not a developer and cannot understand all of the acronyms being used these days, but I can write some html and squeak by, but this has got me perplexed. It's something I have to sort out with support from Wordpress and/or Gravatar, but it seems that software that's been around as long as Gravatar has, ought to be more user-friendly.
Gravatar has come a long way since I first used it many years ago on bulletin board sites.
Now it's possible to integrate it with almost every major (and some minor) sites such as Google+, LinkedIn, YouTube, etc.
Gravatar frees up a lot of my time when my demographic or photographic changes need to be made in my profiles on sites I'm registered on. As a freelance writer, it is of utmost importance that clients be able to get in touch with me, and Gravatar makes it simple and easy for me to update my profiles on almost all of the platforms I use.
My time is very limited and inputting my information into every site that I am registered on takes up more time than I have. Besides, it is very boring and gives me a headache to have to repeat that process over and over. Not only that, but having to go through all the sites I am a member of, plus all of my own sites and change my information is very overwhelming. The ability to do all of those changes, including changing my photograph that identifies my brand, is amazing. Gravatar has saved me a lot of time and headaches.
