What Mike said.
If not stropping a newbie's new blade is "conventional" wisdom, it's not because it's a superior methodology. It's because the newbie is likely to undo the previous work performed on the edge. A few bad strokes on the strop and the edge is no longer the one provided to you by the seller.
Once you've mastered the basics, and certainly after or even during your first shave, you'll want to strop. Stropping is good. Should you strop after a shave or before the next one? I do both. An edge should be considered a living, breathing thing. It will change even if left alone, and the blade should be stropped before each shave and between passes.
