It's like coffee granules . . . goes into water one way, lands up being something different afterwards. Still coffee, but different.

Having been one of the very regular contributors of recent past, I would tell you a slightly different story as to why the forums died.
One of the reasons was simply that everytime somebody contributed something, they got shot down in flames and were accused of 'hi-jacking" a topic. Funny thing was though, those same members who complained about this were the first to complain when the forums were quiet.
There are countless reasons though . . . . . .
A typical "be yourself, just differently" situation . . . . .
you see now, spoken like a true information seeker.
While I am almost entirely of the same view as yourself, I think the problem is that people were never really allowed to have opinion. Whenever a person did, there was a particular Mod who was very quick to pour water on said opinion.
Anyway, like you say, the forum is not what it used to be, or even what it could be. The only way (seemingly) to get people to give input, is to bring up the cultural differences in the country, or alternatively to jump down someone's throat for sharing their opinion.
But, this is of course only my opinion.
So, I was chatting to a friend of mine the other day about experiences we would still like to have. She "accused" me of being the biggest reason I have not "ticked" some of the Items off the to do list.
On reflection, I would have to say that she was right, I do sometimes (often) not allow a situation to play out and subsequently opportunities go by unused. Now I'm not talking about dodgy situations. Just those times when even with a familiar playmate, that one specific boundary is left intact . . . . .
Anybody else have something similar?
