I knew of the convenience of RSS but never used it until yesterday. I downloaded Vienna (free RSS reader) and it works beautifully. I normally check a number of sites many times throughout the day which is time consuming while inevitably missing something. Now im on top of everything i care about and its fantastic. If you havent dabbled in RSS i strongly recommend giving it a try either through Safari or Vienna. Vienna has a number similar to Mail that shows up on your dock of how many new feeds you have not read. The only thing i wish Vienna had was a smaller time increment of auto refreshing (minimum is 30 mins). Otherwise you can just click its refresher icon manually.
