We have been working on developing RSS reader since last 8 months. We felt google reader is not for everyone and we wanted our rss reader to be used by anyone... who may not understand RSS. While implementing the RSS reader, we have learnt a lot and one of them being the power of RSS. I hope what we are building helps a lot of people. Check out http://multiplx.com

I tried with my multiplx.com - an alternative for Google Reader and I am not able to get the traffic i need neither my post came to limelight in HN. So, it all depends... not sure when and what picks up..
