I have been using Feed on Feeds as my RSS agregator for the past month, but I have decided to go back to using Bloglines. I liked the clean lines of Feed on Feeds, as well as the ability to host my feeds on my own website. However, it uses Magpie RSS to parse the feeds, and it can be quite persnickety if the feed does not completely validate. This limited me in the feeds I could track, as well as causing headaches every time I tried to update the feeds. Also, I couldn’t get the silent update feature to work. I tweaked my crontab file until I was blue in the face, but nothing worked. Overall, Bloglines requires less maintenance or headaches on my part. Feed on Feeds has great potential, but for now, I will give it some time to mature.
