Let's say posterJohn created a topic about:
"The best way to get from Zakopane to Gdansk?"The first post is answered by postieEwa and is on topic and answers the question. For example:
If you don't know Poland yet, taking a bus would be a good idea. There are many private transportation companies and you won't have a problem choosing the one that fits your needs. Another option is to take a train, but you'd probably have to go to Krakow first and then get a direct connection to Gdansk from there. Last time I took a train from Krakow to Berlin and it was fun too :)
Then another person, posterDontcare, replies to Ewa, quoting her:
postieEwa: I took a train from Krakow to Berlin
Hey, I'm from Germany. Sprechen Sie Deutsch?
posterDontcare: Sprechen Sie Deutsch?
Ja wohl! It was a great trip. Are you from Berlin?
postieEwa: Are you from Berlin?
Yes. If you visit Germany let me know. Are you a student?
posterDontcare: Are you a student?
I'm not a student yet, but I'm trying to get a scholarship in Germany. Maybe you have experience in that?
etc. etc.
And off-topic conversations between postieEwa and posterDontcare begin. Then another poster joins them and the discussion of 100 posts actually has 1 (ONE) relevant answer to the topic starter's thread.
In fact, the private conversations could be done via
Private Mail. But, obviously, most users don't care and don't respect the person who started the thread and stray off-topic.
It could as well happen without quoting attribution, but in reality it's harder then. Agree? :) If not, then do you care?
