Asking for advice for trips or to be hosted by hospitable people on your way or ar your destination, it's one of the blessings of internet. I see many interesting threads and learned very much since I'm researching a foreign trip, not only by own threads, but also scanning others.
Itinerary, cheapest hostel, what can I do in San Fransisco during a stop-over, the question may have much relevancy for the poster. So does the answer.
But often I think: Quite easy to ask others to do the Googling. Or: the question is so vague, the destination unknown (I want to go to Florence, any experience, what can I expect?) or one doesn't tell what's the (main) purpose of a visit (No I go for the sunbating, no cathedrals and hiking in the mountains please...)
At first I gave serious answers to some of these last questions.
Sometimes people react and after some more reactions there's a vague outline of the real queston, wish.
Sometimes people say Thank you for your great help. No more.
Sometimes there are no reactions.
I like feed back to know if my advice/help/suggestions are useful, appreciated, or only stupid talk of a would-be traveller.
I like clear questions.
I go to America and what are the must-have-seen's? This is no question but showing laziness.
a. Google it yourself
b. When do you go? How long? Transport? Alone? Tent or car-rntal or...? What are your special interests? Budget? And twelve other details to inform the audience what you are looking for.
Then I tell you to go to the Skywalk at Grand Canyon on needle-heels (is this word really existing) and then you react that you've only hikingboots.
So one of the twelve other details. Tell that you like hiking, or cycling or ballooning or ...
I am much more motivated to reply seriously and detailed to people who take me, as potential audience and possible advisor, seriously.
And to finish:
I never see feed back after three weeks when the trip has ended. 'Guys I finished the trip, thank you again for the good advice. And then you mention some concrete issues and/or tell about changes (e.g. there's no more Panama-canal).
(although the feedback will sometimes go by mail)
I think, acting like this makes the Forum more serious, professional and reliable. You don't scan redundant items.
I meet this phenomenon more or less on Forums like Thorn Tree (Lonely Planet) and Travellerspoint
That's why I post this thread there too.
