One of the worst things about Twitter is the inability to find old tweets. The best way to backup tweets is using a tool like Bundlr to save conversations, a conference discussion or a product feedback on Twitter.
You could already clip tweets using Bundlr, but in the latest release we simplified the workflow. Here’s how you can clip tweets into a bundle:
On the Twitter website, click on Bundlr’s browser button…

…and notice the red Clip tweet link at the bottom of each tweet.

Pick the bundle to where you want to clip the tweets…

..or create a new one.

Finally, click on the Clip tweet link of the tweet you want to save…

…and the tweet is automatically saved to your bundle. If you go to the bundle page you’ll see your freshly clipped tweet:

To clip more tweets, just press Keep clipping on the widget and select other tweets. The bundle you picked last time will be selected by default.
