Thanks for the tip on savings.
$60 a year for normal unlimited storage for zenfolio, cyber monday makes it half that --- but I would likely choose a competing photo hosting site. Smugmug's basic is always about half that price and offers unlimited storage and is a long-time company (12 years!). Flickr offers so much more for so much less. Even Amazon storage, Dropbox, Copy seem to offer more photo storage solutions. Zenfolio looks like it is catered to the aspiring professional who wants to share photos with clients -- but those options don't kick until you move up the pricing tier.
Luke -- Zenfolio looks to work fine from my network connection, perhaps you were hitting it during peak traffic on cyber monday?
