From Mike Davidson:
The full-text vs. excerpt debate is one that deserves its own blog entry — and will probably get one — but for now, my opinion is that people should do whatever makes the most business sense for them. At least one person at the conference mistakenly thought I meant that full-text feeds were evil and no one should use them. I can only attribute that to a bit of what I will now call The Jason Fried Effect (anybody want to do a Wikipedia entry on that?) — that is, when confident words are mistaken for unconditional advice.
