One of the great things about foursquare is using your friends tips to find venues to visit and things to do there. Today foursquare has rolled out a major change to their to-dos, making it easy to mark those venues and things to do for your reference in the future. They’ve also made it easy to add to-dos from any site via the “Add to Foursquare” button.

Every venue now includes an “Add to My To-Do List” button above the map that pops up a window where you can add an optional note to your to-do. This adds it to your to-do list, which is accessible from your user profile page. Sadly, foursquare still only shows the to-dos in your current city. You can also access your to-dos from within the foursquare app on your mobile phone.

You can add any tip to your to-do list by clicking the “+” that pops up when you roll over it. Like the “I’ve done this box” before, the check button marks that you’ve already done an item.

The “Add to Foursquare” button, first used by the Wall Street Journal, is now active for everyone. You can create a button from any venue or any tip using the “<>” embed button. This presents a pop-up with code that you can copy and paste to any website. It creates a button like the one below. When you click it, a window opens that allows you to add the item to your to-do list.

The item page for each tip (found by clicking the tip date) has also been revised, showing you more information about which friends and other users have done the tip or added it to their own to-do list.

To make it easier to find places to add to your to-do list, foursquare has also revised the search page to allow you to search “near” a particular city. You no longer need to change your “current city” to search for venues in a different place.

This is a great change that makes it easier to remember the great things you find on foursquare. Releasing the “Add to Foursquare” button to everyone will help to increase foursquare’s visibility on a wide variety of mainstream sites. Hopefully many of foursquare’s partners will begin using it immediately.
