In reply to LakesWinter:
There are more people than ever in the hills in winter. And there's a lot more coming in future. They'll be coming from further away, without the local networks of experienced climbers than climbers of today. While standards at the top are higher than ever, I'd guess that the average experience level of today's winter climber is lower than in the past. I think this trend is likely to continue, and no one can stop or change it - and maybe they shouldn't.
Obviously there is nothing better than your own experience or that of respected peers to inform your decisions of where/what/when to climb. Even then there are no guarentees.
And there's legitimate concerns about the "sat nav" effect of people suspending common sense because their beloved device tells them to drive down the rail tracks etc.
But there's also a danger of patronising sensible people by saying they can't be trusted to make a balanced judgment based data they know to be imperfect and subjective. This applies to existing UKC data like voting on grades.
And there's evidentally a parochial "keep it under your hat" fear of in-nick venues getting mobbed by "the hordes". Would it be better if they went and hacked up some out of condition crag instead so the in-the-knows don't have to queue?
Also I think many climbers might be more honest about reporting that they climbed a route out of condition if it was anonymous. This could be useful for conservation awareness.
Conditions are always going to be controversial, especially as the climate becomes more unpredictable, but that's not going to keep more climbers with less experience and local connections from coming. Would it be better if they had more information (even if subjective) or less?
