By definition, I read stuff and only links that I think will be useful make it into Trello Also, because the links are categorized well, it removes the need to keep going back and reviewing further etc - I only access the info as and when I need it.

The key is in organization & labeling It's not just a random pasting of links into the board I use different lists to categorize broad categories of content & cards as "sub categories" which makes it easier to go back to as and when i need it.

It helps that I always have Trello open in a browser so its quick and easy to paste stuff into the board wherever it belongs and move on with my life.
