I like Prismatic a lot, and used it more than a few times a week. From the user perspective, here's where I think they failed to execute well.<p>1. They did almost zero marketing of the product. Almost of their marketing was based around their engineering prowess (maybe this was by design).<p>2. The sites they scraped and indexed for content were largely B and C grade. For example, I never saw content from the NY Times. Google News scrapes this site, so from a disappointed user perspective I chalk this up to laziness on Prismatic's part.
