By now, you are probably familiar with Facebook and what it is; in fact, chances are that you are already addicted to it. In their own words, Facebook is a social utility that connects you with people around you.
The success of this site is a great example of Web 2.0: we have passed from being strictly consumers, to become great contributors of the Internet content. On Facebook, users can publish almost everything: posts (editorials), photos, videos, create groups and even create classified ads.
Facebook started as a school-only site; but since opening the site to everyone, they have experienced and continue to experience very impressive growth, with an even more impressive user engagement. Let’s look at the numbers:
- Has 43 million active users, with the number doubling every 6 months!
- 50% of users return to the site at least once a day.
- A typical Facebook user is 25 years or older.
- 5th site in number of Page views
- 1st photo site
Impressed yet? Well, lets see the numbers for in Canada in, one of the countries with greatest reception of Facebook:
- 6 million active users (1 in ever 5 Canadians!)
- 9 out of the top 30 cities (in terms of memberships) are Canadian including
- #2 for Toronto (with 800.000) users
- #3 Vancouver
In fact, a Development Camp series (2 conferences) hold in Toronto in August and October respectively, drew crowd of 1000 people in total.
New, Exciting Opportunities

As a Web Developer, I’ve frequently have had the need to make asynchronical function calls.
Usually, you need to do async calls when:
- Function takes a long time to process
- There is no need to present a response to the user
In this example, I will be showing some code I use on my Facebook Application (Network Trotters) to update the users profiles.
As a quick contextual background, user profiles are cached on Facebook’s side, and periodically I need to clear the cache so it is updated. This action can take a bit of time when you have a high number of users, but it doesn’t really require any response to the user.
There are 3 main things you need to do to create an async call:
- Create a delegate with the signature you would like
- Implement a Function with the same function as the delegate
- Call the delegate

In this post I will discuss how I implemented the Profile Management for Network Trotters .
Profile Management Generals
As an application developer, you get the opportunity to place some information in the user profile page. Specifically you can set a Profile Action (link below the Profile Pic) and a Profile Box.
In your application you basically tell the Facebook platform where it should get the FBML/HTML that defines both the Profile Action and Profile Box. It is important to notice, that Facebook will Cache this FBML/HTML, until you specifically tell them to refresh it.
So in summary, you set the user Profile from your application, but you have to build a mechanism to refresh the users profile periodically.
I am using the Facebook Development Toolkit as the Facebook Platform API wrapper; and the profiles are set by using Urls.
.Net Implementation (one of many)
In my implementation, the profile management contains 3 main components:
- Profile Content Page
- Setting a user profile
- Refresh the profile
