I started up an application development blog specifically for building FBML applications. I don't get to update it often (I've got a lot of work on my hands and I don't earn anything form it), but I do try to update it when I can. If you need help or have questions about Facebook's Ajax or dialogs, that'd be the place to go for help. If you've got questions after looking at it, feel free to ask me here or on the Facebook Developer forums, of which I am one of the moderators. Hopefully my blog is of some help!
I think still you can update your blog with the latest information . i found the contends are old when i checked your blog. and you provided some coding also which is good for many users.
The contents of my blog are not out-dated in any way. I use the code on my blog daily in my own endeavors. If there were any major updates or something stopped working, I would know about it.
