I have check Ticket #3070 (defect)and Technorati ID, also i searched my rss files to check the tags, but the vaildator is saying that

This feed is valid, but may cause problems for some users. We recommend fixing these problems.
*line 24, column 28: guid should not be blank [help]

*line 33, column 3: wfw:commentRSS should be wfw:commentRss [help]
