Web app: Picnik - online photo editor

Last month I discovered a great online photo editor called PXN8. A few days ago on TechCrunch I saw they too like PXN8 but say there's an even better online photo editor available now called Picnik. I checked it out and have to say it's very sweet. I asked my friend (and photoisseur) Ray to check Picnik out and he was quite impressed by some of the advanced editing tools provided in Picnik. The site strikes me as a better designed and slightly more intuitive version of PXN8. I haven't done a comparison of the features between the two but I'm planning to use Picnik for my photo editing needs now.
