Well, "SELECT *" is only evil if your application relies on a specific column
order to function. The moment you change the table layout and you're using
"select *" your application will cease functioning.
My app uses tons of select *, but then I wrote an object mapper that queries
the information schema at startup - so it's aware of table changes and
adjusts accordingly.
