After looking again at Eric, Eric does seem to be the better researcher in terms of sheer material. Matthew Boylan seems to be the better interviewee.
We should attempt to court them both, The arguments they use are good, but can be refined. A few of the arguments Eric uses are things we've discussed before, are fallacious and don't work. Much of it is good, however. Some things were discussed that even I haven't seen. We can use more people like him.
