Let's just break the cardinal rule: don't blog when you are upset.
Both my sessions for this year's OSCON were rejected. Not just an improved, updated and Ajax-ey Building Web Applications with Tapestry, but a very differently scoped Metaprogramming Java with HiveMind and Javassist.
For O'Reilly ... if it doesn't say Ruby, it's not open source enough! This is doubly dissapointing, because last year's session went well (and turned out to be lucrative), and OSCON is held in Portland, OR ... just 10 minutes away by MAX.
