No but then I've never asked either. I have met lots of people that get information on trip advisor. We went to China in May with Viking River Cruises, before the trip I did lots of research on cruise critic and when we returned found out there were posters there from the same trip. It is a small world.

No. I suspect the majority of posters here are american and we tend not to spend time with other americans when we travel. No reason not to - we just don;t focus on that - and tend to end up in conversation with people from other parts of the world.

And Fodors has never come up. (I don;t ask them about Rick Steeeeeves either.)

I hope I will be there.. would love to coincide.

I'm not seeking Americans out, but certainly seem to find them!

Other people walk by and just say hi to us...do we look that American (don't answer that!) we don't seem to be dressed any differently than anyone else. Why not ciao or bonjour or guten tag?

I did ask one other couple if they were on Fodors, but they were on a foreign travel forum.

I like the idea of asking how someone knew about an activity of place.
