Many accidental DBA's are developers and may be doing both roles.
Technically i'm a Stealth DBA (I do dba things cause we, as a company, need it...even though its not in my job description, and noone else is doing it).
Topics that bridge both worlds are VERY beneficial for me.
Plus, it can be a more holistic view of Sql Server. ie. Here is how developers and DBAs can coordinate to avoid the worst problems.
At the end of the day its all about the server running as fast and smoothly as it can while being as flexible to end users.
