I've been lurking on LW/OB for a while but thought I'd sign up. I'm currently doing a philosophy degree which you might expect would make me feel unwelcome on LW (which is often fairly anti-philosophy) but it's actually really great to come across a group with a similar view about how to do philosophy as me - I tend to come across more interesting philosophy ideas here than I do in classes.
Anyway, just thought I'd say hello.
Welcome to Less Wrong! Don't worry too much about our being anti-philosophy. We're more against the common views held and methodologies used by philosophers than against the field itself. That is, the areas philosophy investigates are worth investigating; the bashing is reserved for the way philosophers go about it.
