Sciencebase Guestbook Q&A

I’m afraid I have disabled comments on the blog. After 15 years of tedious trolls and scurrilous spam it really wasn’t worth the effort to maintain. You can follow me on Twitter and Facebook if you wish to engage in meaningful discussion. Thanks! If you use the hashtag #sciencebase or just @sciencebase me I should spot your updates and be able to reply if I have something pertinent to say.
