This needs to be more than just a service. You need to think about about the psychology of it all. I come across words all the time that I don't know, but I don't look them up. I have plenty of excuses why not, but those don't matter. Just like loosing weight. The point is that to 'win' you need to address the psychology of looking words up. How is this going to be easier than looking them up my self. This service would be useful for many people, if it just e-mailed you the next day all the words you didn't know and definitions, and then sent you an e-mail at the end of each week. If you really wanted to market it well, I'd do this and then do research on word exposure frequency like being exposed to it every day for 2 days, then every 3 days for 6 days, then every week for 6 weeks, then once a month 5 months or something like that. And this strategy increases word retention by 65%. These numbers are all made up, but that's the gist of it.
