Heinz Tschabitscher has been writing about email, communication, and useful technology since 1997.
First, How Does This Sound?
The new-device smell and comfortable feel of an inbox freshly emptied.
The flood of happy endorphins in your blood’s stream as you understand something new.
The irresistible chuckle rising from toe to tip of the tongue of a surprising connection.
Yes, you may have to pick two out of the three — and the choice might not be entirely yours to make.
Oh — Hello! I’m Heinz Tschabitscher
My name is Heinz Tschabitscher, and I do aim to provide you with the above (at least). It is a pleasure meeting you!
Since 1997, I have been writing about email, communication, and useful technology at MiningCo.com, About.com, Lifewire and here at La De Du — always from the user’s point of view and read by millions.
So, what will you find here?
- Step by step instructions (say, on typing em-dash and en-dash on Windows, how to find large attachments in Gmail, how to type “squared” on a Mac or how to insert the current moon phase emoji) that leave nothing out and include screenshots where useful with content that is well-researched and tested to work.
- Reviews (say, of website safety checkers, sites that convert between time zones for you or free online image compressors and other top picks more) that focus not on new features but on how useful a product or service is for a given purpose.
- Explanations that bring technology to life (say, the best email signature image size or which characters are allowed in email addresses), because the deeper you dig, the more interesting even the mundane often becomes.
- Irreverent drawings (say, of a fox evidently subscribed to a La De Du RSS feed), of course.
