Social media shortlinks
This site hosts shortlists of links to your social media profiles, to make it easier to list them all on other social media profiles.
That way, you can just include the link to a collection on this site when creating a profile somewhere else.
Also, when you add or remove links to social media accounts, you only have to update it here.
It's all free, and will probably be supported by discrete ads at some point. See the examples page for layout at the moment.
