I have spoken in public perhaps over hundred times and yet before every presentation my hands shake and I have a funny feeling in my stomach. If I have to use a hand-held microphone you will even be able to see the shake.
This is not nerves or me being afraid. This is adrenaline pumping through my body. This is perfectly normal so I just accept it and go ahead with the presentation.
Joomla 3.4 was released last month and just as with every major Joomla release there were beta and release candidates made available for testing over the preceding weeks. Those special releases are made specifically for Joomla developers to use to both test the changes in the upcoming release AND to check that their own code is still working as intended.
The web was meant to be read, not squished.
This isn't the way to test a responsive design.
