As to tilly's recent (and most distasteful) experiences, I believe the ramifications are potentially tremendous. However, you're asking about how I feel about my job.

First, I work for an educational institution, so they're very familiar with, open to, and supportive of the idea of sharing knowledge.

Second, I didn't sign jack when I took this job.

Third, after revisiting some of the code I recently wrote while under tremendous time constraints, I can't think of one person who would want to claim ownership, including me. Which is kind of sad. I worked really hard on that code.

If things get any worse, I'll have to ask you to stop helping me.
