If you have an OAuth application, remember to register apps with all the variations of your app name, i.e., AppName, AppName.com, www.AppName.com, etc.
You're only going to use one of them. The rest of them are to prevent someone else from registering the name and impersonating your app. Twitter: Can you please build in better verification that it is the actual owner of the app that is registering the app? Something like the email domain of the registering Twitter account must be the same as the domain in the app's URL, and then send a confirmation email to that email address to activate the registration. Or reasonable facsimilee thereof. Twitter folks, can you please delete the SocialOomph app entry so that I can register it in my @socialoomph Twitter account and use it for implementing OAuth on my site.
