I was interested and then surprised on visiting the site that there seemed to be quite a few listings. However, most of what I clicked on had no nutritional information (a few lines of "?" instead). I would be much more likely to add information if I could easily see either a list or table of products which have been added (i.e. name and a picture) but have no/missing data. Also as rpedela has mentioned, an API would be helpful for adding and consuming the data.
