Gravatar has expanded its offering to also include rich profile sharing, along the lines of LinkTree. It also have an API so that the profile info can be integrated into apps and websites.

Gravatar has two new updates.  One is that you can now use it for an online profile with links to your social accounts, which totally makes sense.  The second is that it now has new payment features. That doesn’t, by default, seem like part of a global avatar service.
