I am one of those laymen who wish to go beyond the popularizations of Greene, Randall, Smolin and others. I thought it might be worthwhile to follow the blogs of scientists/researchers such as Peter Woit, Lubos Motl, etc. Unfortunately, those blogs are little more than mud-slinging contests between string theorists and their critics. Motl's blog in particular is a harsh rant against anything and anyone who dares question string theory. Smolin, among others, is called an idiot, imbecile and crackpot. Woit's blog is better. He doesn't resort to personal attacks. I wish these folks, Motl in particular, understood they have a huge audience of interested readers, folks who don't know the ins and outs of all the math. It's dismaying when you find out that Harvard profs such as Motl are no better than fundamentalist preachers, who go on the rampage against anyone questioning "The Truth" as they see it. Thank goodness for Physics Forums.
