When I was writing my SA post last night I was doign some googling about selective inhibition and one of my searches took me to the new website, and the content didn't match what I'd searched....that's when I noticed the change.  

Overall the new design, I find it cleaner and easier to navigate.  Up on the top right they link to their Facebook page, and I don't know why they'd want to do that:

At least their Twitter feed, which is also linked....they tweet on a semi regular basis.

To be 100% completely frank, I don't care much about what web sites look like....businesses have to have them of course, but beyond that ....meh.  The question I have is...."Why change it"???  The old site worked fine, so why to go the time energy and expense.  

The only reason that makes sense to me is that they're expecting more traffic....like a family doing renovations and a big clean up before the family comes in to stay over.
