Why is it that string theory has become such a favoured paradigm? Have theoretical physicists deluded themselves? Have they been pressured by social forces to blind themselves to other possible theories? Is there a behind-the-scenes string-theory conspiracy that is propping up a pseudoscientific house of cards?
...An essential criterion is whether there is experimental evidence to support the theory. We have a description, called the Standard Model of particle physics, which agrees with observations exceedingly well, with a few small exceptions. A reactionary could ask, since the present model works so well, why bother to look for something new?
From this perspective, not only string theory but almost all models of new physics are currently devoid of experimental evidence in their favour. But there are many experimental hints and theoretical motivations telling us that the Standard Model cannot be the final answer. That deep conviction is what drives all particle theorists, and not just string theorists, to seek a more fundamental and unified description of nature.

I never asked, since the ping list doesn't necessarily exist, but do you want to be added? Also, all should note that I plastered some new posts into the 'blog tonight.
Wow, with all that going for it I certainly hope this is a big idea that won't die.
Thanks. Keep me posted.
