In reply to nicnic:
The main difference between publishing and posting the location of a bothy / howff / doss on the internet and simply telling someone about it is that you quickly lose control of who has the information online, and it remains a public record long after the event.
A conversation held round the bothy fire about other dosses is only between those present and so you can make a judgement about whether you tell them or not. And if you do, its private - someone walking into the bothy in 6 months time wont be given the same info (unless you etched it onto the wall, or it has really funny acoustics....)
A blog entry or post stays on t'interweb, and can be viewed by anyone long after.
Also, though most estates do tolerate usage, they also ask not to have the location published online as too many people using a building can cause problems. I can think of a few that have been closed for this reason apart from Poca Buidhe as unfortunately a significant number of bothiers really don't respect the bothys or their surrounds well.
Most of the non MBA bothies I know of have come from chatting to other bothy goers, or been found by accident which would be the traditional way the information was spread. I've been put onto a few (some that worked out, some that didn't) but part of that trust was that I'd be selective with who I passed the info onto.
It may seem unfair in a modern context where we are used to being able to get any info we want with minimal effort on our parts simply by consulting google, but it's a healthier way IMO.
My point is that if you publish information about a bothy, doss, howff etc on a blog, forum etc, it stays a matter of public record for a long time afterwards so you have no control over who uses that info. If you stick to private conversations (either in the real world or online), you can make a judgement over whether the person your speaking to is OK to tell, or not and part of that will be whether you think they'll tell all and sundry themselves. Months/years later, someone else looking for a boozing den can't happen across your blog entry / forum post and ruin a great bothy that way.
