What if I had a Design challenge which I needed help on? Where could I find the best support and creative thoughts. There so many platforms out there which all provide for a different audience.
So having made that conclusion, I’d look at what kind of project I have on my hands and try to find a fitting platform for the problem I’m dealing with. Some choices are pretty straight forward. For instance you’ll probably get the largest audience via facebook since it has the largest community.
But maybe I’m dealing with a technical problem? I’m might try to go to Instructables.com which have loads of different DIY projects and a great community to help you out, although forums do great as well they are focused slightly more on a specific subject.
On the other hand I could be having a funding problem, in which case the obvious way to go is a crowd funding site like Kickstarter or Indiegogo.
Finally collaboration works great on basecamp or google docs.
In the end every problem has a different solution, which is not strange since each and every problem is different. Though if you want to reach the full potential of your project you shouldn’t stick to one platform.
If I had a project I’d make sure it was available on a lot of platforms, so as to reach a wider platform, more and wider range of feedback and convenient for most any situation. Defining it more closely: a basis in Facebook (which everyone uses daily) a crowdfunded part to define and/or create a market with buying customers. And a blog! Especially the blog is important, since you can change the way in looks to fit you project, you can get feedback easily, and make it feel more personal.
