Some observations from this and other forums:
'Threads' start to fray! I've noticed many times - here and elsewhere - that while the initial responses to a question are usually 'on topic', there comes a point, sooner or later, when it starts to wander off-topic. Sometimes the wandering is interesting, sometimes it isn't.
While there may be an issue with asking clear questions ( and that's not always easy if the OP is not quite certain what the problem is), it is often the case that those with expert technical knowledge may not always be able to communicate that knowledge clearly and concisely in writing - particularly if it is highly technical.
We're an argumentative, disputatious, opinionated.....and knowledgable lot....for better and, sometimes, for worse!
