A project idea for project ideas?
If I have ideas for new kinds of websites or applications... What is the best place on the internet to get opinions on my ideas and possibly find people who would help me or join me in realizing them?
The community like SO's would be the most sutable for these topics, because it is the community of professional programmers, who are able to estimate feasibility of a project idea and to appreciate interesting ideas. On StackExchange, up/down votes would be great for separating the most interesting ideas and useful opinions/advices. And the 'reputation' feature can be useful in many ways too.
Unfortunately, simple Q&A format and the design of SE websites in general is not very suitable for this purpose.
So, my question is: Where can I reach the best community of professional programmers that, unlike the StackExchange, has a support for this kind of topics?
