For the past month or so, I’ve been working on updating my list of ecommerce acronyms and abbreviations which first appeared in my book. Last year, I began noticing some new ones popping up on resumes and published a list of those ealier this year. I thought it might be useful to add some of the newer ones I’ve been seeing, and put everything in one place create a sort of “master list.”  I am still in the process of adding definitions to all of these, but this should help in the event one of these slips your mind, or even if you’re just curious to know which ecommerce acronyms are considered cool. This will be a living, breathing list that I hope to update on a periodic basis. If you see something missing that you think should be included, please add it in the comments and I’ll add it to the list.
