Tiles, cards, widgets, gizmos, grids - the name does not matter. What matters is the functionality and principle.
Be very careful of creating a interface method that forces all content and functionality into an overly consistent way of working. Consistency can make things look pretty and is vital, up to a point.
The trick is to learn when what you are doing needs a new way of doing it.
For example I have seen many websites and intranets that needlessly using the 'widget' approach to allow the user to build pages themselves. It failed for the BBC and Google and I've yet to see it work effectively for any company - no matter how many times companies and less expeirenced UX folks use it.
The use of 'tiles' to present 'like items' is, on the other hand, standard practice. Often it's just referred to as a grid view (although it's best not to expose that to the users). Most ecommerce sites use this. A tile view on sites like pinterest is just a grid view with variable vertical heights. The underlying principle remains the same but the presentation is tweaked in a good way.
I hope that helps.
