If you’d like to make it easier for people to contact you via your blog (or MySpace or whereever you can post code), Windows Live Messenger has a site where you can create a nice-looking button in seconds that will get them in touch with your Live Messenger screen name. You could even add the button to your email or forum signature, and there are multiple button designs, colors and taglines available to customize it for your needs.
I don’t like that the button’s source code exposes your Live ID, and thus your Hotmail email address, with no effort by Microsoft to obfuscate the email. That’s the kind of mistake Google makes every time it launches a product, and I expect smarter moves from Microsoft. As a result, clicking the button up there will launch an IM window, but you’ll be talking to my good friend email@example.com, not me.
