Freelancers vs. Agencies
I don't think agencies are bad, but for most work I've ever needed I think just hiring a freelancer first, seeing if they're good, then hiring them some more is far more effective than going with an agency.
For big companies I understand why a giant agency makes sense, but in my opinion in the modern world a very very small group of people can far outwork a large group of people.
