Hi Skyler - couple of tips
Firstly you have some questions here that are 'if yes then...' type questions and they're mandatory so if the answer is no people still have to complete them - next time think about a N/A for these.
Secondly - nothing wrong with getting responses internationally but you really need to get that into your survey so you can distinguish them.
Now you've posted on a UK website you'll be getting feedback from us Brits and you won't be able to distinguish the results from Americans.
Since social behaviour and the way social media is used varies internationally this will skew your results. Doubtlessly you will have a part of your project where you need to assess your results critically (the things I'd do differently next time bit) - this would be a good observation to make there.
An example of different use of media by geographic entities would be the way US and the UK picked up mobile phones and text messaging.
10 years or so ago cell phone coverage in the US was still rather patchy and so pagers were still widely used there. The UK being smaller meant that coverage was better sooner and so SMS text messaging was used widely here much earlier much as it is today.
It's always worth asking international responders which country they are in
