Whatever the percentage, Schmuckley has a point. But aren't we missing out on the fact that this is a hobby. As with any hobby there are various degrees of how you experience your hobby.
It depends on a lot of factors:
Time: what gets left after work, homework, familytime
Money: if you're a college student or already have a job
Dedication: some can have a high level of addiction, for others it's more of a casual thing.
Interest: some do it for fun, for the thrill of competition, to collect cups and medals, to collect points or pure interest in the HW and SW.
The result is that you can't start labelling people. The community - which we may think is big, but compared to other hobbies (on a global scale) is peanuts - should therefore belong to everyone, whatever their main drive to overclock and irrespective of ones financial capabilities.
Why would we take away the joy of someone getting their first gold cup with 2 points simply because he benched some obscure HW at stock settings? I'd say well done. One doesn't know how long that person had to search for that item, how much time it took him to save for a decent powersupply or an SSD. So who are we then to critisize that person and take away his joy.
If there is no openness in all this, people will start to drop out. You'll end up with only a couple of fanatics and the entire community will eventually die out. These persons should realize that the major manufactures of HW don't care about them. If you think they do, think again. Yes there are always friendly employees at ASUS, Corsair, MSI, ... but in the end those guys have to report to their manager. And all they care about is sales (and if they don't, the shareholders will ;-) ). Thus the bigger the community, the longer it will last.
So to all my fellow OC'ers I would say, have some respect for each other. Take a minute to try and see the world through a fellow OC'ers eyes, or think back how you got involved in OC'ing to start with ... It'll give you some much needed perspective.
