Hello.

It's nearly impossible to get consistent get data in and out of a web app on the client

Back in February, I presented at TwitterDevNest about getting data in and out of Buzz. The slides are now available on SlideShare. I covered WebFinger, OpenID, Buzz feeds, Pubsubhubbub, and Salmon. I also promised to open-source the demo code, which I'll be pushing to Github later today (covering most of the topics except Salmon).

Concerned about Facebook privacy? I've created a Facebook application called "Know Your Privacy" to help you understand how third-party apps access your profile data. It highlights potential risks and offers common-sense advice. Find it at http://apps.facebook.com/knowyourprivacy/. Your feedback is welcome! Disclaimer: This app is for informational purposes only and doesn't imply any misuse of data by installed apps. It's not professional advice; contact authorities for accurate information. Resources on identity theft are included.

Google's new data protocol, GData, has me wondering about the future of Blogger. Will Blogger integrate with GData? Blogger already uses Atom, so will that make integration easier? Or will Blogger's slow pace of development prevent them from adopting GData anytime soon? I'm skeptical.

I'm building a tag directory separate from my main content. This approach aims to enhance indexing and provide a centralized, dynamic display, similar to Technorati. It allows me to tag my directories and offers a new way to present related information. Check it out and let me know what features you'd like to see!

I've created a basic JavaScript Object Model for OPML, which you can find here: http://www.kinlan.co.uk/AjaxExperiments/opml.js. It's not entirely finished yet, but the core structure is in place. I plan to write proper documentation soon.

In this part of my series on my AJAX application, I'm discussing the impact of external APIs. My use of APIs has made me realize how much more API access I want! I'd love to see broader API availability from feed/blog companies for statistics, retail companies for catalogs, news corporations for news feeds, and search companies for both results and more interesting APIs (like Yahoo's). Essentially, I want a central directory of companies offering these services, recognizing that I'm a consumer of their data. I'm also realizing how many APIs (REST and SOAP) are out there that I could leverage. I envision adding more dynamism to my apps, like analyzing blog post keywords to see their popularity, potential ad revenue, and related keywords. I could then cross-reference this with other sources to give viewers more feedback, such as related blog importance, link counts, and other connections. I could even offer localized product information, best buy deals, or second-hand options based on keywords. This isn't revolutionary, but I need help finding lists of companies that offer web APIs and useful RSS feeds. Readers, please share your knowledge!
