Amazing, lots of questions if you don't mind answering
1) is this written in python 2) if yes, does it use feedparser 3) how are you storing these feeds in the database 4) how are you handling CDATA or html based feeds that return lots of html, do you sanitize before storing or store directly in the database as a CDATA string? 5) how do you handle edge cases and anomalies across different feed providers?
