Some people are running into problems adding SWF content to Facebook Profile pages. There seems to be a caching issue with some versions of Internet Explorer.

This issue showed up for me when developing a Facebook application that has a Flex component in the user's profile. I found that clearing my IE cache solved the problem for my purposes.

As reported on TechCrunch and Mashable, Facebook just released an iPhone version of the site today. I'm impressed, the user interface is clean and very slick.

I don't have an iPhone and don't plan on getting one any time soon so I will probably never experience the full benefits of this interface, but why not use this site in your normal browser?

I had a chat with Mixbook CEO Andrew Laffoon the other day and heard about some of the new things they are working on.

Mixbook is a Flex-based application where you upload photos and collaborate with friends to create virtual scrapbooks. I think the neatest part is once you are done you can order a physical copy of your book bringing your digital creations to life.

I attended the Facebook Developer Garage in Toronto earlier this week and have noted some key points that I found helpful and think other developers might be interested in.

There were about 450 attendees from the Greater Toronto Area. By a rough show of hands it looked like 40% developers, 40% business people, and 20% other who are just interested in Facebook in general.

I swear that Facebook has somehow hacked my Outlook calendar and found every meeting where I am demonstrating a Facebook application because it seems this is the time they like to tinker with the service. Almost every scheduled meeting I have had, something in the Facebook platform breaks 30 minutes beforehand.

Today the site starting acting funny around 12:00pm EST and now it looks like the whole site is down, or "upgrading" as it says on their home page.
