Reading your favorite sites or keeping track of topics through RSS is one of the best ways to optimize your online reading. Not only will reading through RSS save time by not having to visit sites but you will no longer need an extensive bookmark list, there will be less loading time, and you won't have to sort through as many advertisements. Even so, RSS has problems of it's own. There are a lot of potential issues, but a big one is how easy it is to add more feeds. This is not a problem in and of itself, but you can easily overwhelm yourself simply by trying to consume too much. Another problem is that it becomes a constant flow of information to you so by the time you what originally intended to new posts are popping up and you can get stuck reading for extended periods of time.
