Contactify allows you to easily create a simple form that people can use to reach you via e-mail rather than posting your actual e-mail address (or an image of your e-mail address or a version of your e-mail address with things spelled out with goofy characters). So here's the link for my blog e-mail address:
This would be much cooler if I could put a widget directly on my blog, but it's still pretty cool. Actually, it would also be cool if you could just send an e-mail to my Contactify ID, but then there are already a bunch of services that offer that.
What's super-funny is that on the "Contact Us" page, Contactify provides an actual e-mail address rather than forcing you to use their service -- makes me nervous that they don't trust their own product enough.
