>You'd better strike while the iron is hot. (Is that a blacksmith's slogan, BTW? - I just realized that I don't know the origin of the saying).
That's the cruel world of technology (blacksmith as the technocrat here) twisting the language and introducing the artefacts of their trade into common speech, full steam ahead (sic!). Such expressions are really the fifth wheel of the language, and I've had a buffer overflown with them.
The above paragraph is a random pick from what I say to anyone saying that we geeks talk our tecnho jargon and introduce our own words into common language. Now it was OK for blacksmiths, horseriders, railroad guys and seamen to do that, and somehow only we get criticized when we do the same thing.
