I agree with what appears to be the general consensus - it is the wheels, not you.

I have had perhaps 1 broken spoke from 1977 until a few years ago, mostly on high-end hand built wheels or very good quality machine wheels (I verified/adjusted tension).
After a small hiatus from cycling I started commuting on a Bianchi Milano with the mediocre factory wheelset (that I did not tension) and I broke 5 spokes in 8 months.
After re-tensioning the wheel, all has been fine.

That reminds me..... I need to check the tension on the front wheel of my new Norco.....
