You are arguing against deleting unwayed segments, but not against 
making them into FIXME ways, right?

Don't worry I am not about to do anything, I am just talking. I do 
accept that unwayed segments can be an interim result of work in 
progress, like Harry Wood said - you trace something from Yahoo and only 
later make ways from it. But I maintain that once a segment has been 
sitting around unwayed for some time, it is practically dead.

Personally, I almost never use other peoples' segments for anything 
because I always think that I haven't got enough information. Is this 
really the segment describing the road that I believe must be there? Or 
is it the railway line next to it? Or is it the edge of the forest that 
begins at that road? The segment is worth nothing to me if the person 
who added it didn't provide information.

If I may make a suggestion; you should really make ways from your 
segments even if you do not know the name of the street. At least tell 
us that it *is* a street and not a river, lake, forest, landuse area, 
railway line, or footway!

As I said - I very seldom touch other peoples' segments without knowing 
what they are intended to represent.

1.5 million, actually.
