Putting your email address up online is an invitation for spammers to scrape it and bombard you with offers for penis enlargements. But often times you'll want certain people to be able to get in touch with you, so it's nice to have contact information you can leave up the web. Contactify makes the process of creating your own contact form extremely easy by creating an anonymized url for people to reach you through. All you have to do is leave the link; people who want to reach you will fill out the form and their message will be delivered to your inbox.
Though TechCrunch worries that there's no simple way to turn the form off, I was able to edit my account information easily. Thus, if the url that I'm using gets swamped with spam, I can just switch to a new one.
