I used to be a HUGE fan of Tweetie until Tweetie 2. Some of my favorite features were removed like the dark theme and I don’t really like the new retweet feature and the quote feature only lets you use “via” instead of “RT”. Anyway, this is a really kewl video from the developer speaking at Standford University back in May of 2009. It’s a kewl inside view to app developing and more support for why some apps should be paid and not free. Oh, and be prepared, it’s 30 minutes long.
