A big part of building a successful and lasting application isn't just about getting users to try it the first time, it's also vital to get them to come back again and again. To help make that easier we're launching a set of tools to enable users to bookmark applications so they can easily navigate back to them, as well as receive updates from applications in a new communication channel -- Counters. We've also added a column to the permissions FQL table so that you can easily see which of your users have bookmarked your application.

You can prompt your users to bookmark your application in the following ways:

• You can use the fb:bookmark FBML or XFBML tags, which render an Add Bookmark button on your canvas page or Facebook Connect site.
  


• You can call FB.Connect.showBookmarkDialog (for your Facebook Connect site or IFrame application) or Facebook.showBookmarkDialog (for your FBML application) inside an onclick handler only. (Only show the dialog when a user has clicked something indicating they want to bookmark an application -- don't pop it up on its own.)
