OSCON is the best conference in the FOSS sphere. It’s great fun and I always walk away having learned a HUGE amount. It’s also a great place to meet and talk with lots of really smart geeks, which is something I would always recommend.
Please send in your talk proposals. I am working on the PHP track. This year, there are some more general tracks - Web Apps, Programming, and Security. These are great for those talks that cross borders.
Go here to submit your talk:
Don’t be afraid to submit a talk: there’s always room for people who haven’t given a talk before who are passionate about Open Source.
