Well, I'm taken aback!
Why would somebody asking some questions get under your skin so much (and why has it got under the skin of certain other posters such that they have vented rather than answer the questions).
However, let me address your points.
1) Is anything necessary? However, I believe that polls like this sometimes give a clearer view of what the balance of opinion is that discussions where some voices (mine included) dominate.
2) Yes, there is uncertainty and debate about what the definition means, so let us see what the consensus is.
3) There are stretches of canal where I might like to moor sometimes, but these stretches are always occupied by boats that seem to be there for weeks on end, and keep returning with monotonous regularity.
4) It isn't specious. There are places that one can commute to, and still CC. Manchester is one such place.
I'm not trying to batter an opinion down your throat. You don't have to read the thread, and in any case, I'm asking for opinions, not giving them out.
