Here’s something to watch out for if you have the Skype browser button. If you use a content management system to edit your website and happen to have phone numbers on the page you are editing, it’s possible that a whole bunch of Skype code will be injected in around each phone number.
It’s not a big deal to strip it out if you’ve only got one or two numbers on a page, but if you have a page full of worldwide agents and each of their phone numbers get the Skype code treatment it’s a real headache to get rid of. So before editing any pages containing phone numbers, switch off the Skype browser button.
Personally it find the idea of an application taking control of web pages and inserting it’s own code before displaying them to be a bit intrusive. Surely web pages should be displayed the way the site owner wants them to be shown.
