Why we created the ‘TL;DR Wikipedia’
A couple of centuries of human progress have made our daily life enriched with definitions. It’s quite surprising how many of them we meet every day.
You can experience it with this little experiment:
Open an Excel sheet in the morning and during your day each time you encounter a concept you’re not fully understand add it up to the doc. By the end of the day you’ll be surprised by the doc’s length.
Wouldn’t it be nice if you could grasp any concept thrown at you in 30 seconds?
When a neurotic guy like me meets a new concept he usually goes to Wikipedia, skim it for a few seconds — only to realize that there are more concepts that needs to be learned first.
Sometimes Google comes to the rescue with its ‘Features Snippet’ feature. it is useful but it’s basically a twist on Wikipedia.
And sometimes concepts are just too ‘small’ for Wikipedia to allow for their own definitions.
Enter dinf.net:

In dinf any concept is limited to 500 characters. Definitions are uploaded & rated by users. Sometimes people upload their own definitions and sometimes they share definitions from around the web.
We believe that in every person there is a dinf or two inside waiting to be published online for the rest of us to enjoy.
Happy dinfing :)
