Blogs are a Commonplace Book

Commonplace - Wikipedia, the free encyclopedia: "They were essentially scrapbooks filled with items of every kind: medical recipes, quotes, letters, poems, tables of weights and measures, proverbs, prayers, legal formulas. Commonplaces were used by readers, writers, students, and humanists as an aid for remembering useful concepts or facts they had learned. Each commonplace book was unique to its creator's particular interests."
