I think that it depends on what the ultimate word sounds like and if it is easy to pronounce/spell/remember. I have found that the prefix "i" or "my" work better when some kind of ownership/personalization is there. For instance, iDiet is great if you allow someone to have an online dieting program, eDiet is better for selling diet related stuff.
