Most people on the forums don't seem to know how to play wizards or maybe only a couple of sub classes (Diviner/Invoker/Abjurer it seems). Wizard will never be good at damage although fireball is useful every now and then.
Treantmonks guide is OK but a few spells have been rated wrong IIRC.
Wizard 101. Dont use damage spells generally, use spells that target cha saves or wisdom saves, avoid direct damage spells generally (exceptions fireball/lightning bolt), and avoid spells that have con saves.
I agree.
Martial classes are now so much efficient at dealing damage that Wizard must find something else to shine.
I play an evocation wizard until level 11, at the end I was having a few evocation spells prepared.
