Open Source Patent Donations?

patspam writes "As a software engineer I come up with patentable ideas every now and then, ideas which I'm not interested in pursuing myself but which I'd like to keep out of the hands of private entities/patent trolls in my own personal effort to defeat software patents. Should I patent the ideas and donate them to some sort of open source foundation? Or just blog about the ideas so that the 'prior art' exists in the public domain? What's your strategy for fighting against restrictive software patents?"
