THSS has become a caricature of what it once was in terms of edgy humor. Staffers are largely one-trick ponies whose schtick is well played out by now, and largely uninteresting to begin with. Bits and general banter has been mailed in for years now.
The show still only shines in two areas:
1) Interviews -- Howard still, IMHO, is one of the best interviewers in the biz. THey aren't all gold, but when they are, they are better than any other media outlet interviews in terms of substance and genuineness.
2) Music -- specifically from birthday shows or tributes -- the Bowie tribute album simply blew me away. In-studio can be hit or miss but is still largely hit, especially with guests like Billy Joel. Lady Gaga was amazing.
