Twitter = Discovery (Part XXXIV)
Read Bob's LinkedIn profile here. According to that profile, he is the Consulting Product Manager at Oracle. Cool.
His blog can be found here. I believe that is his first post as well, Oracle BI Server Modeling, Part 1- Designing a Query Factory.
Lots of other groups or individuals blog at Oracle which is very helpful. I haven't found anyone from the OBIEE group who does so...which sucks for us.
The only other person I know of that is even related is Tim Dexter (and crew) over at the BI (formerly XML) Publisher blog.
While it doesn't appear that Bob is technically on the OBIEE development team, I will say it's a good start.
