twOpml tool
    • This is the app release of the Twitter Subscription Lists project.
    • It runs as a Tool in the OPML Editor, on Mac or Windows.
    • It generates OPML subscription lists from your Twitter followers, in a form that can be read into a feed reader app, such as Google Reader or River2.
    • The feeds do not have cloud elements, so they are not real-time. That's coming later in the process. :-)
    • Once installed, you can use it as a web app, or choose a command from the Tools menu in the OPML Editor.
    • Update: Lifehacker just ran a review of the server app.
    • If you have questions or problems -- and even if everything works great, please post a comment at the bottom of this page. It helps to know if things are working, and if there are problems I want to help you get the app running, especially immediately after it's released. Thanks! Dave
    • If you haven't already done so, download and install the OPML Editor.
    • Choose Tool Catalog from the Misc Menu, and click on the Install link next to twOpml.
    • Confirm that you want to install when the dialog appears.
    • After it's installed this page is displayed in the web browser.
    • This app is built on the Twitter API which has several implications.
    • The first time you fetch the OPML for a user it may take a bit of time because it has to make a series of calls to Twitter to get the information. Twitter returns followers in batches of 100. So if you follow 3000 people, it must make 30 calls, each of which takes a few seconds. For users with lots of followers, it adds up.
    • Unless you have been specifically whitelisted by Twitter, you will eventually hit a rate-limit and Twitter will stop responding for a while. When that happens, wait a while and then try again. Or request to be whitelisted. The gnomes at Twitter are friendly, and seem to say yes as long as your intentions are good. :-)
    • There is a cache that lasts for one hour, so if you make a change, following or unfollowing, it will take some time before it's reflected in the OPML.
    • We also store a copy of each OPML file you generate in the twOpml folder in the OPML application folder. This can save you some time. It also keeps a calendar-structured archive in a sub-folder.
    • You can also generate OPML for a Twitter user as follows:
    • 1. Bring the OPML Editor app to the front.
    • 2. Choose the Get OPML command from the TwOpml sub-menu of the Tools menu.
    • 3. Enter the name of the user and click OK. (It defaults to friendsOfDave.)
    • 4. The browser displays the OPML.
