It's personal information used by banks, websites, government offices, and more. Any identity thief or hacker can use that, along with your IP and MAC addresses, possibly even your screenname if you reuse it, and can narrow down who or where you are. Once they have your name or street address, and that can easily be done, it's not a huge step to get other information. Your social security number, for instance, if you're a US citizen.
If you think that's far fetched, keep in mind 4chan autists located Shia LaBeouf's ridiculous "art project" (a flag) using nothing but a livestream pointed at the sky. And they did it more than once.
If you put personal information of any kind on a public forum, you are a moron.
