I've been working on this for the past 3 months or so full time. Rails 3 + MongoDB. We're having trouble getting users to understand what a 'bookmarklet' is, so I'm having to create browser extensions (God help me when I get to IE).<p>It's marketed more towards women and the products they buy (they shop way more than men), but it can be used to save and compare just about anything that has a web page. I would love to know your first impressions or how to make it better/easier.
