Oh No They Didn't! People who have more exciting lives than me... FAQ - Journal Entries. LJ-Like is a feature which allows users to share their support of an author's entry in various ways.
By inserting the LJ Give (10 LJ Tokens), Twitter (Tweet), and Vkontakte (Like). With the exception of LJ Give, clicking the button of an LJ-Like service in the entry will share that entry to the social media platform selected by the user. LJ Give works differently. Each time a LiveJournal user clicks the LJ Give button, 10 tokens are transferred from the user to the author of the entry in which the button appears.
Placing the <lj-like> tag into an entry without setting any parameters will display all available service buttons.
