You know - maybe the original poster doesn't want to travel a long way to somewhere remote only to find that the bike's not appropriate for the job?

This is a forum, [at least last time I looked it was]. The idea of a forum is to share knowledge.
The folding-bikes sub-forum seems to have a pretty good reputation as a place for friendly and supportive behaviour—so as a regular here I'm pretty disappointed by your cheap shot at the original poster.

Participants deserve respect and good treatment—however trivial or slight their question may seem to you. That's the beauty right there - one can ask pretty much anything without prejudice, whether it's about the best way to mend a flat tyre right up to queries on how to rebuild from the frame up; the point being it's all fair game however simple or complex the input. I don't recall reading an 'Only serious questions from seasoned bike-heads will be tolerated' rule when I signed up...

Simply put: I resent this sort of impatient and condescending tone—there really wasn't any call for it.
Bambi's mum had it right - if someone's query about downhill braking on an unfamiliar bike sends your blood boiling - you could choose not to read it... Or maybe, if you absolutely have to read it, could you resist the urge to bang off another thoughtless reply, unless it's something that will actually bring something to the table.
