One reason may have been that .SVG never gained the popularity he anticipated.
Actually, it's plenty popular (it's a W3C standard
, after all...), it's just that other programs do svg better.
Last time I checked, Eve was severely lacking in features and svg export didn't look like a hot selling point especially when Sodipodi
gave much prettier results and was almost as abandoned.
and Illustrator (and some others I forget now...) are ruling the vector art world right now, so Eve is (sadly, some may say) left way behind.
