Snapixel.com is going out of business at the end of this month. That's too bad, because their free on-line portfolios are first-class in my opinion: simple, clean, classy.
Snapixel had a decent monthly newsletter, too--better than some photography magazines.
One aspect of Snapixel is similar to Flickr, except better. It's really too bad that they're closing their metaphoric doors.
I'll have to find somewhere else to host my on-line portfolio now.
