I don't want to open an off topic about "user generated content" web 2.0 just means easier tools, not better quality of the content.
About Fyp, what I meant is not that you will steal my idea, but I won't trust some user I don't know, but I'm just one, maybe there are a lot of people they will.
Moreover, remember that Fyp staff will be responsible for the content of the forum.
I have this idea, a pen whit a lighter, we suppose it doesn't exist, and it's a low tech piece of plastic. I can't produce it myself, I even can't make a prototype, so I need help. I write on fyp "ehy I have a great idea, but I can't do it without you help, I need an engineer and a designer". So fyp give me a restricted area to discuss my idea, I choose two users because I think they're ok, but when I tell them my idea, they steal it and produce it.
yeah I'm done. What can I do? I havn't patented it, should I try a legal action? Against the two users and against fyp? Sure I will lose, but you will go through a legal action.
Another stupid example:
User A: Ehy I think we should create a site for selling and buying things
User B: Great idea, I'm a web designer, I will do it for you.
The next day: "B-bay.com an idea from user B"
Or maybe: "H-bay.com an idea from the hacker"
Ok, it's all about trust between the users, but we're not talking about the "home do it yourself forum", we're talking about money.
If I have an idea, I will share it only between people I trust. Naturally these are just suggestions
I don't think anyone was trying to affirm that web 2.0 means better content in terms of quality (for sure it means a wider and more accessible content), as I said, in my opinion It's just a matter of ease of access and possibility to interact (for people with a "standard" IT-knowledge). It may sound simple, but the user interface and appearence have a great impact on the attractivness and usability of a web-site (or an application, or probably almost everything).
Personally, I think that the gap between what we call web 1.0 and 2.0 is quite evident (newsgroups/forums static/dynamic web-sites etc...).
About FYP (or similar projects):
I think that hackers won't be interested in attacking such a web-site before it has actually produced something important and has a lot of users, but that means the web-site has a much more organised and protected structure.
There are many ways to protect a communication over the internet, a password on a forum it's quite a basic one, but you can easily look for people on the forum and then use skype, msn or encrypted protocols to talk to them.
I don't want to minimize the problem, I think you are talking about a crucial aspect of our project, that will eventually determine weather it will be successful or not. I just think there are a lot of possible and effective solutions.
About trusting people: I dont' think that you would totally rely on someone before having at least an idea of who you're talking to. What you're saying could happen also with a partner in any kind of business, as Paolo said it's a matter of trusting people or not, and you choose who to trust (in the real life or on a forum)...
Maybe it could be helpfull including some kind of "identity confirmation"... for example to sign up in some professional forum you need to provide a "visura camerale".
More about trusting people: people behind a monitor tend to act different in real life and in a business in the real life you have a lot of tools to protect your business or your ideas.
Fyp could be a powerfull tool to meet professional skills and sharing ideas, but it in my opinion it can't be just a forum, you need something else.
You need to promote the forum, it's impossible to google it
