It started out this way because IE8 and IE7 didnt get media querys so if you did mobile first then you would get a mobile layout on these older browsers. So it became best practice to build mobile first - remember that then responsive design was very much in it's infancy, the're were a lot of ideas floating around and none had been properly researched in depth. Since then polyfills have been created to allow media querys in legacy IE so now it really doesn't matter if you build mobile first or not.
 
What's important is that you don't think of specific devices like mobile, tablet etc, there's so many grey areas and devices of different screen sizes. You should enure that your UI looks great at all conceiveable screen sizes.
 
I tend to build out my largest screen UI's first then reduce the screen size and adapt the UI accordingly. So I'm not using mobile first yet my UI's look every bit as good on the smallest screens as those designed using mobile first principles. This is not a superior workflow to mobile first, but neither is the opposite true. I do often find though with mobile first designs that the large screen equivalents are lacking and still have elements still in a mobile kind of view, which I dislike - why show a collapsed nav menu on large screens, forcing the user to make an extra click to see the contents? This I feel though is more down to the dev(s) who built the site rather than the principle. I'm happy to work in both ways, but I just find I get slightly better results starting with large screens.
 
There's an argument that you load in less CSS for mobile devices doing mobile first.. While that's true, in almost all cases you are optimising in the wrong place if this is concerning you. On an average project my resulting CSS is around 10-15kb Gzipped. That's the size of a small image. Perhaps if i went mobile first I could shave a KB off. which in the grand shceme of things is nothing - we're talking milliseconds.
You're better off spending time optimising images, serving up smaller versions to small screened devices, lazy load your images.

Your Weight converter isn't working properly.
 
 
 
 
I agree very much.
Your homepage is way too empty and you can place all your converters there.
You current site is functional enough but lack the 'looks'
You need to improve your UI elements. You can get some meaningful resources at http://365psd.com/ (yes, they are free)

You're always welcomed.
 
To get your website/work reviewed, you should post in Website Reviews and Feedback category.
I myself received valuable and positive reviews by doing this, and you may get the same.

Minimal look is appealing.
These are many but minor things that, in my opinion would add more visibility and details to your great work.
 
You can reduce the size of logos in 'affiliation' section and align them (also the 'clients' section).
Reduce the line-height of paragraph texts.
I like the parallax style.
You can always add extra vertical padding/margins.
'Connect with us' background color makes the text harder to read.
And the video sextion needs some elaboration.
Animated icons in 'what we do' section are superb, just give them some more space.
 
I hope it helped

Thanks Robert.
I guess that rest of the the world is already too busy
 
And good luck with your blog (it's really great).

T-shirt design is quite colorful and glamorous, which doesn't match your original product.
I think you should play with flat vectors (like the ones you;ve used in video and as icons) along with your logo 'couplelizer'.
 
Your site seems quite functional but it lacks an attractive interface (main page).
You can always improve the typography and add some spacing to all the text fields.
