Let me explain: I recently received an e-mail from a guy through my contact page. He called himself “Basil”, and with his permission (or without), I'd like to share it with you:
i think you are a mullet who sets out particularly lofty views of design when in fact you know so little about it (as some one who is in fact formally trained and employed in the industry) i would reccomend you keep the design mumbo limited i look at your logo and cringe d squared the two for the squared in a different font this proves in my mind that design is in fact purely a litter generating profit making misguided endevour if you had studied you might realise design has a lot less to do with marketing and more to do with developing products to suit peoples needs and one does have to consider the target market when doing this but selling it should'nt be your only focus design responsibly for fuck sakes. this logo is irritating me d2. pixel width ahh. design goes far beyond graphics and marketing think of all the producs you interact with and rely on every day ahhh man i suppose i just hate ignorant people going to the next step of philosophising about design when they can't even do it in the first place sorry to piss on your battery but i can let shit like this go on unnoticed if it means anything i probably could'nt do the html coding for a website anymore but i could (and have) design the b'jesus out of it grey is the new pink. chow
After the first sentence, I almost got pissed off… However, I continued reading, and by end of the message I was smiling broadly 
With your permission, I'd like to quote myself (from my site) to point a few overlooked things out to Basil (whose real name turned out to be Stephen).
From my about page, in response to “lofty views of design”:
I can't claim to really know anything about the fundamentals of design. After all, I have no formal training in any form of design. I do however at least think I know what design is...
OK, so I don't really have any authority. Fine by me - the field of design simply interests me, and I like to share the wonder of that interest with others.
From my about page, in response to “litter generating profit making misguided endevour”.
I like designing. In fact, I like it so much that I spend substantial time and resources designing things I might never get paid for.
There are LOTS of things I could do to generate far more profit than design, but I love it too much – and besides, it's fun 
From my about page (again), in response to “developing products to suit peoples needs”
design is about arranging things in a way which improves the subject / object / matter being considered. More practically, design is applicable on multiple levels. It's about making things work well. It's about making things look good. On a deeper level, it's about making people feel good about things.
You're completely right, it does go far beyond graphics and marketing. Architecture and automative design are good examples. More on the overlooked end are things like paperclips and door handles.
Anyway, I replied to this gentleman, recommending that he check his spelling, and asking him whether he'd care to recommend a different font combination for my “cringe-inducing” logo. His reply?
actually no mr hattingh i would recommend that for your own corporate identity you design an original script but then i doubt you are capable of using software outside the realm of photo editing and web design packages or in fact using a pencil and pen like the professionals.
Damn, I was afraid that he was going to say that :P. My drawing skills suck, but I tried, and here's what I came up with... What do you guys think?

On the second point, Basil, I'm afraid that you've assumed slightly wrong. The business which I'm a co-founder of is a Microsoft Partner in the Enterprise space, and I built my first PC from scratch in 1984, so sorry…
To Basil:
Design is, as you rightly mention, not just about graphics and marketing. In fact, I'd say that these elements make up a very small part of it. Design is applicable everywhere, whether a meal is being cooked (with the chef as designer), or whether you're crafting a mountain bike disc brake mount by hand. Dude, thanks once again for the laugh. I don't blame you for criticising, just check to see if you can make a positive contribution before you do. In this case, the custom font was a good suggestion….
