DailyLit, which offers entire books over e-mail and RSS in daily serialized chunks every day, is now offering information from Wikipedia on various topics.
The free service would be perfect for people who are short on time and don't mind digesting literature and information in 5 minutes at a time on their handheld.
The Wikipedia-based topics DailyLit is creating "tours" of major world religions (22 installments--compared with the 260 installments for Moby Dick), "Wine 101," presidents of the United States, "Best Picture" Oscar winners, famous poets, famous women in history, Greek mythology, famous inventors, and wonders of the world.
Each installment has a brief intro to a subcategory, such as Buddhism in the religions tour, and a link to the relevant Wikipedia page. Wikipedia's content is available for such repurposing under the Creative Commons license.
