PostSecret

Online since 2004, PostSecret is an art project that invites people to mail-in self-made postcards on which they anonymously confess a secret or a wish about their life.

From a CNN.com article:

The voices presented on PostSecret can be troubling, tender, hilarious or heartbreaking. Some of the art and graphics may have taken less than 10 seconds. Others take hours of time and effort.

Online Art-Zines

Here are some of my favorite ["underground"] art magazines online. Most you can download and save for viewing offline; all are great viewing. Some are in Flash (.swf) format, and some are .pdf. Each issue presents work from young artists around the globe - USA, Germany, Romania, Russia, etc. I keep my downloaded issues always nearby to kickstart me into "create" mode. Click around, view or download a sample of each issue, then bookmark the sites for your pleasure as you need.

Illustration, photography, etc 'zines:

There are lots of others, but these will get you started (and inspired).
