I still write C code and GUIs for stuff, but doing it in PHP,SQL,Perl is just so much quicker and easier for things that my C programming is not as frequent as it used to be and my C skills are getting stale. I'm not in need of a client-side app as much anymore nowadays, the browsers are so capable that it's not as necessary to do heavy client-side apps much. I'm not discrediting client-side apps, it's just that the demand isn't as high anymore.
