Pinterest just made DIYers very happy with the 'tried it' button

Pinterest has introduced a “tried it” button that allows users mark recipes and projects that they’ve tried.
Beyond adding a check mark to the posts you've tried, you can also leave comments to remind yourself of something about the project or to provide others some extra insight.
The list of checked off projects will be found in users’ profiles.
This new feature will be accessible to all over the coming weeks.
