Zivity, the adult social network and media site that describes itself as a “community-powered showcase of female beauty”, has laid off 1/3 of its staff, cutting back from 22 employees to 15. (Again, 1/3 seems to be the magic number – Jive and Seesmic have both laid off about a third of their staff in the last week).

Zivity is in a unique position as one of the only venture capital backed sites with “adult” content (i.e. nudity), and has raised a total of $8 million. Earlier this year the site scored Napster co-founder Jordan Ritter as its CTO.
