I was doing RSS submission a while ago for one of my site and was searching for some good RSS directories. I found plenty of them online and segregated good ones from them. However while submitting my feed url I found that plenty of these sites dont actually function well. Most of them are broken links, outdated or not updated since long time.
I eventually ended up submitting my site to handful of good directories which accepted my site without any problem and submission was very smooth. I am sharing the small list with you. Hopefully it will be useful to my fellow webmasters. I request you to share your experience and add the names of good sites to this list and create a helpful resource here. All the best!
