transformer full-wave rectifier topology
(OP)
I have a colleague that professes using the center tap of a transformer as the positive voltage node instead of ground is superior, having "read it somewhere." See attached drawing.
Is there some advantage to using the alternate topology (lower schematic) that I'm missing? As far as I can see there are no advantages and one big disadvantage, which is having double the voltage relative to ground.

The transformer insulation will be happier with the traditional architecture (top).
Considering the final score, it's no wonder that the traditional architecture is the traditional architecture.

If we're allowed to add two additional diodes, then the top circuit can become a bipolar power supply.
Float the circuit (delete the ground connection). Then ground whatever node you please.

As far as the advantages OperaHouse listed, we are utilizing neither... I will try to convince my colleague to switch to the standard.

I've been reading about galvanic corrosion this morning, but have a lot of learning to do! Any suggested resources I might check out?

Yes, you need an electrolyte. There's forum338: Corrosion engineering where you might get some hints, although they're a funny bunch over there.
