I blog and write stories for the Atlanta Journal Constitution about radio and TV. I've been covering radio since 2001 and TV since 2005. (Tom Taylor here knows me well.) I just posted a piece I did for print and online about Sirius/XM if you want to weigh in... I listen to Sirius/XM fairly regularly, esp. Stern, Sirius Hits 1, the 80s and 90s channels and the Highway.
