These guys are doing a disservice to the American public. Imagine how much more used stuff could be sold on craigslist if their interface and experience was better. One statistic is smartphones, which can resell for as much as $200 after two years of use, yet most people leave them in their drawer. If a platform existed where selling and buying was easier, then people that are too busy to use craigslist would have an alternative to give new life to the stuff that is just sitting in their drawer. More people could own higher quality products instead of buying the cheaper new crap as an alternative. We consume way too much new crap. I bet there are >10 million used iphones sitting in drawers, while cost conscious consumer resort to buying the Motorola Triumph as that is all they can afford for $200. I know a lot of people love craigslist, but it is time for something better. It is time to create an efficient and "beautiful" consumer to consumer marketplace that everyone wants to use. Craigslist is huge, but it serves only a fraction of the potential customer base. I would bet more people would use it if some of its fundamental flaws were fixed.
End of rant... Let me know if you agree. I am actually doing something about this and am always open to input and help...
