I like the piece-meal way because:

• It gives me longer to digest each idea.
• Since I tend to go back and skim earlier entries in sequences like this when a new one comes out, more frequent updates indirectly tend to improve my retention.
• If I stop reading in the middle of a huge long article, I'm less likely to pick it back up again later. With short articles, I'm more likely to get it properly finished before I get interrupted or distracted by something else.
