Just learned about that recently -- it's a retina display issue (fix going up tonight). Thanks for pointing it out!

I have heard of it and used it myself.

The primary difference is really the intended use case. Where ETM is focusing on highly-specific (usually on a nutrient/caloric basis) meal plans to hit a target nutritional intake, we are more centered around using general preferences about food (ingredients, cuisine, cooking methods, etc.) in a "browsing" capacity -- currently in the form of recipes aggregated from other sites and bloggers. The goal is eventually to also incorporate nearby restaurant dishes.
