You can download my second ttytter extension now from the github page. This lets you add the links in tweets to your Pocket (formerly Read-It-Later) account.
To use, you first need to create a file named .pocket in the extension’s directory and add your Pocket username and password in two separate lines. In ttytter, just type /pocket <tweet id> and the link in the tweet will be added to Pocket. If no links were found in the tweet, the link to the tweet itself will be added.
