A Rails consultancy (I used to work for) in Atlanta called Highgroove also implements ROWE, going so far as to incorporate it into the way they deliver to the customer. It was a great way to work and operate as a business.
I often take a couple of shots of the same thing just to experiment; probably a symptom of growing up shooting digital. I guess you're just banking on randomness preventing dupes from showing too often or manually removing them.
Dupes are definitely possible - though rare in my case. Not only am I randomizing which photos get thumbnailed, I also randomize their order on each page load. I do screen the photos before they get deployed anyways.
Last I looked, both Chef and Puppet were meta-tools that launch all the other third-party tools I don't want involved. Are either of them solid enough now to actually replace the system package manager? Can they answer questions like "why does /etc/foo exist, which package created that?"
Friend of mine was graphing out all of the connections (using Graphviz) and found some interesting patterns. Ultimately you can say the same thing for "Science", "Knowledge", and even "Mathematics".
I know of at least one change that isn't a new product for consumers but isn't a new change to the store displays either. Nor a giveaway. Might be what this is.
