From use of X/x to mean “kiss” and O/o to mean “hug”. Use of “X” to indicate a kiss attested since 1763, preceded by medieval use of an “X”, which was then kissed by illiterates to indicate a signature. Use of “O” is more recent, and presumably created by analogy (e.g., X/O in tic-tac-toe). Speculative theories on precise origins abound, including folk etymologies.

XOXO (eXtensible Open XHTML Outlines) is an XML microformat for outlines built on top of XHTML. Developed by several authors as an attempt to reuse XHTML building blocks instead of inventing unnecessary new XML elements/attributes, XOXO is based on existing conventions for publishing outlines, lists, and blogrolls on the Web.
