Wow, really? As both a developer and a small business owner, I'm fairly repulsed by this attitude. How, in this economy, would you not be willing to learn technologies that would provide you the most job opportunities. How would you respond if an employer insisted you learn .NET? If I encountered someone with your attitude while interviewing job candidates, I would end the interview on the spot. Enjoy unemployment and obsolescence, dipshit.

Cheers to this. From my perspective, we can't spend enough time researching cures for cancer...just my selfish perspective, I guess, but I've lost far too many family members to it already...
