Because the XML file conforms to an existing RSS standard (there are actually a few, and it is possible to be compatible with all of them in the same feed), it can be consumed by a wide variety of RSS reading applications, including Firefox and Safari. Indeed, the practice known as podcasting involves a customized RSS feed that includes a link to an MP3 file that your podcasting playing software (such as iTunes) will automatically download. RSS is a pull technology, meaning updates to the feed aren’t pushed to users; instead, the users’ RSS reader will periodically ping the feed to see if there are updates.

All that cool stuff that Adobe builds for us into the framework must be downloaded by the users of your applications. 6MB. This one hurdle, which can radically increase download times, essentially restricted Flex’s value to comprehensive applications, rather than web pages or widgets (such as RSS readers that can be easily added to any page). , not the browser’s cache), meaning that applications that had been, for example, 300KB, can now weigh in at 40KB! And another hurdle has been surmounted!

From my experience running LA Flash, I knew this consisted largely of two items: calendar events and blog posts. That is, our front page functions best and provides the highest-quality experience to our members when it delivers information on upcoming events and good blog posts from members of our community. So, adminlevel users may promote any event to the front page and make it sticky (so it remains there until the stickiness is removed), and they may give certain of their member bloggers front page posting rights so they can contribute to the main community landing.
