I am quite annoyed that I didn't know the signs of drowning, having very young children and having watched water safety videos and taking my children swimming, but no advice on how to spot this. More preventative stuff.
I think it should be made a bigger deal of. Often holiday pools are not guarded and if everyone around knows the signs then someone can be saved.
Knowing is half the battle. The other half is fighting. Spreading awareness would be the fighting part. ;)
Things spread insanely fast on Facebook. If a few parents shared this website and their also-parent friends shared it with their friends it could easily get millions of views within several days. And parents would share this information.
If you think it should be made a bigger deal of - why not make it a bigger deal? Message your school district representatives about swimming education, especially identifying when someone is drowning. Start a funding for a public pool for your town/city, if one doesn't exist, and support the school organizing "field trips" to the public pool to provide such an education.
You'll likely get ignored. So start talking with other parents and make it a large enough issue that it can't be ignored. I don't think many parents would be against their child being taught how to swim, practice pool safety, and learn a life skill that could save someone's life. The main issue is getting them to think about it in the first place.
The hardest part about getting anything done is finding a leader with the drive and ability to get things done. Few people want to step up and even fewer of those that are willing are capable.
