Apple says: "Apps that include the ability to make donations to recognized charitable organizations must be free. The collection of donations must be done via a web site in Safari or an SMS."
Nieman notes: "The first element could impact apps like This American Lifeâ€™s, which costs $2.99 â€” although it has asked for donations via push notifications, which may not fall under â€œthe ability to make donations.â€ But itâ€™s the second line thatâ€™s the complaint for nonprofits. Rather than kick a potential donor into a web browser, theyâ€™d like to be able to accept a gift directly within the app, using Appleâ€™s one-click payment system. Thatâ€™s the way in-app purchases (like buying extra features in an app or levels in a game) happens. Appleâ€™s new rules donâ€™t change anything about that policy."
Great explanation of a Hashtag:
"For those of you who arenâ€™t familiar with the world of Twitter yet, using a hashtag (#) before a word is a way of creating a topic in Twitter. By putting a topic like #boulderfire into a tweet, you are actively joining the conversation. Twitter users can filter on that word and see every tweet about that topic."
