Pseudonymous blogging
Science blogger Greg Laden has an interesting post about the effects of pseudonymous blogging. As the blogosphere becomes increasingly powerful, I think this is an issue that will become more and more prevalent. I plan on writing a feature article about it one of these days, but given how slow I am in researching my feature articles, I don’t know how long it will be before I get around to publishing it.

Ok, Simon - you must be very young in age, and even younger to blogging.
You might want to start with Sock Puppetry, Figure 1. That would be Glenn Greenwald. I’m sure you can google it.
Don’t worry about being slow to research. It’s easy to copy a bunch of emails from other blogs.
