Been reading here for a few months now as a guest, so maybe I can weigh in on this.
I'm almost in the 0.0% on here - 1998 - and that puts me in an interesting in-between place. (Sax experience - played in high school, now I'm three months in taking it seriously now. I can play the high F, woohoo) As far as my regular life goes, I'm married, no kids, dog and a cat, foreman at a construction company. My parents definitely blessed me by making sure I was surrounded by books instead of just games and TV as a little kid, and as someone who's 25 now, I am at the very end of the people who became a teenager without access to social media. My first cell phone still had a physical keyboard, oooooo.
I'm also at the very end of people who've ever used a traditional forum. Reddit is the limit of text based media for the vast majority of people my age and younger. It's a very rare person in my generation who still looks for text based sites to learn from as opposed to video (not to say I don't use video - Get Your Sax Together on youtube has been fundamental to me as I've been getting back into it).
There definitely is other people of my age finding this forum, but they won't find it until they start to have technical questions about saxophone, their embouchure, technique, sax repair, etc. They'll find it through google searches about specific questions like I did, because /r/saxophone on reddit only tells me that the reason I warble on only the G and G# above the staff is because my horns broken or I only have a student Yamaha and not a Selmer, etc. Reddit forums only lead to negative responses, not discussion - the websites designed that way. Video content is too long for simple answers.
The third problem is that maybe only 1 in 100 people my age have ever touched any instrument. And that ratio is not getting better, it's getting worse, and will continue to do so unless something happens with instrument access for kids earlier than high school. Where I live in Ontario, Canada, no one in public school necessarily touches an instrument until the decide to take their one single art credit in high school in Band, instead of one of the several other art classes. Miss that single year, and you may never touch any instrument except your buddies guitar, ever. Otherwise? No one in heck is ever going to just decide to drop $500-1200 on a student-level instrument that they don't know they'll even like. The pool of possible instrument players is shrinking rapidly - and that's a shame, just from a human fulfillment level.
Anyways, that's my two loonies on the subject. 25-year-olds represent.
