I was alerted by another local mapper (nm7s9) to the fact that it is recommended that we shouldn't use abbreviations for road types (i.e. no St, Rd, Ave, Tce, etc, etc). Unfortunately this is excactly what I was doing :-(.

I've just gone through and changed all the ways I've done. It took a few hours but now I'm sure that every way I've ever done is named properly. Thank god for JOSM's ability to save to an OSM file, and thank god for grep!
Lucky it was slow at work today ;-)
