I'd only recently begun following the blog and posts via FB and the RSS feeds, and was extremely disappointed to see his goodbye post. I've totally enjoyed the variety and content Rob has had to offer, and don't believe it would be easily replaced.
I do need to say that the Post is also giving up quantity, as well as quality, with this decision, as I've been amazed at just how many pieces are produced for his blog/column on a daily and weekly basis ^
I wish Rob the best with his future endeavours, and hopes he enjoys his home/Daddy time.
BTW - I think your link is off ... try
