I have been lurking but BOTF's comment about engineering achievement needs a comment - CTRL and HS2 have/will take a long time because of planning issue and trying to respect people's rights and the environment - China doesn't give a toss about either!
FWIW I think communicating via the internet has given people a 'voice' to talk about self esteem issues that they might otherwise have kept quiet about. Personally if I want someone to know I'm feeling low I will talk to them individually but a lot of people seem comfortable to broadcast feelings via Twitter/Facebook/here for a bit of sympathy and to get people to say the opposite about them. They would probably never start a real conversation about it but the facelessness of the internet allows them to be more brash in their approach. So without the internet 10 years ago, you didn't hear it now with it and too many reality tv shows, you can't help but hear it.....some of it maybe real but I think a lot of it is people just wanting someone to say nice things about them and people are getting addicted to that.
Actually you're making me think of a slightly different point re Internet communication. Brought on by the bit you said about sympathy.
I was reading a very long and intimate thread from an American guy who is going through a divorce. he was putting really personal details online about it and of course his soon to be ex wife was coming off in a very bad light.
He got a shed load of sympathy, but my thoughts through the whole thing is that he could of course be lying through his teeth or needing to spin to get justification for his actions.
I'm not saying that he was lying, i have no idea but as usual we only get one side of the story and I'm always amazed how people jump on whichever side is presented online as automatically right.
Now I know they don't do in every situation but there is a generalisation for that trend. Some can get sympathy for anything online.
Not even a criticism really, just an observation.
