Personally, I think the article is half-right. "Let an attorney handle your legal questions" is absolutely correct - Random Guy on Internets should not be making legal decisions for you, and you should always have good legal representation if you're doing business of any sort (even as a freelance programmer).

But sometimes you aren't looking for specific legal advice - you're looking to educate yourself as an entrepreneur. I've learned quite a bit about contracts, business formation, tax law, etc. from my attorneys - but I've also learned a bit from other entrepreneurs.
