Crowd sourcing, is a name for a group of people taking part in something from all over the place. One of the first initiatives like this is open source software, a more recent version is Crowd source funding for businesses. These started as initiatives to give micro loans in Africa and other developing countries. More recently, websites like Kickstarter have allowed everyday people to help get new ventures starting (I plan on writing more about this later).
So what's the deal with the legislation? Well, essentially, this is building upon the momentum Reddit and other websites generated during the SOPA/PIPA protests. Members have decided to create something like an internet bill of rights. The idea is the create a better balance between content holders, private companies, governments and users. In China there's a great deal of censorship and Google and Twitter have both announced censorship based on the location of the user. This type of censorship would have killed the Arab spring before it happened.
OK? but that's not going to effect me in the US. Well, we don't know that. Yes, we have provisions against free speech, but that's against governments censoring speech. It's difficult to know what a private company will censor when this speech is in a quasipublic/private space. Facebook routinely censors groups and speech on their site. Additionally, look at what's happening with MegaUpload.com and their users. There was legitimate use on the website and the Department of Justice doesn't care. The EFF and the hosting company are working to find the legitimate data held on the site.
One of the goals of the act would be to reduce the ability of sites to censor speech. It's clear that this is an important goal of the act. Additionally, there are programs, like TOR, that have been developed to allow people behind censorship to circumvent it (See my post about how TOR works). However, there could be penalties for people that use TOR in the US to help people circumvent the censorship. These types of ideas are what the goal of FIA is.

But that's US based stuff. Yes, sure it is. It seems like most of the users interested are from the US. Many of the users involved would like to see this become a treaty instead of just a law. In that case involvement from many different countries would be ideal and requested. Additionally, there is no reason why this type of legislation should be restricted to the US. These ideas are universal.
