In case you didn't know already, if you don't set up your filesharing software right or if there's a coding error that allows the program to be exploited, random people on the Internet might be able to browse around on your computer. What would they want? Perhaps banking information, personal data, access to your tax records.

If you're going to fileshare, learn a little about the program you plan to use first.

Social Networking Sites

Ars Technica reports on a proposed law in NC that will require parents to sign up for social networking sites (like MySpace) and become age verified before their kids would be allowed to sign up.

This is probably the best way I've heard of to prevent under-age kids from signing up and had the added benefit that the parents will have to know that their kids are using the sites. That way, parents are held accountable too.

So there's a bunch of vulnerabilities in older versions of wordpress. There are other reasons to upgrade besides security.

For example, just going from 2.0 to 2.1, I could see a ton of usability features that made my site much easier to manage. And when I read about 2.2 and how a error in your code wouldn't break your site, I wished I had upgraded then. The very next day, I made a coding error in one of my plugins and my site was down the whole day until I could get back to my home machine.

Either way, besides feature upgrades, each version includes better security so it's best to keep current.
