Switching Back And Forth

It seems that we are making the switch again. First it was ASP.Net, then JSP, and now we're doing PHP. I come from a PHP background so its a welcome change but I was actually wanting to go with JSP. I just purchased the Struts book and was ready to start "going to town". Now I'll be "going to town" with PHP. In all honesty though, I'm anticipating another switch back to one or the other by this time next week.
