vbfeeds.com RSS was broken for the last few days... Thanks to Richard Laniel for pointing that out. I was too busy in the last week and didn't have time to read my Bloglines.
What happened is there was one post that is over 90K and it turned the RSS feed over 200K - I fixed the feed by removing the offending post.
So, vbfeeds.com RSS is back and working fine ... for now :) And I added on my list to implement the feed/size validation.
