I agree with this, but would extend to any and all blog sites ( as well as search engines), whether big such as d-kos, slate, crooked timber, etc, or small, such as Scientologist Worlds, or Duckland.

Many naive bloggers forget that not everyone “plays fair” in blogland–. By clicking on to unsavory sites (ie gambling, porno, etc) a person’s exposes him/herself to risk via malware, but these days some sleazy webmasters will run a “sniffer” app on IP and MAC addresses, and thereby obtain personal information, which can be used for various types of ID theft (that is, if a cracker knows what’s he doing and covers his tracks. If not, he could he headed to jail). That happens even at smaller personal sites.
