After I was done running, I did the same thing. Lifted for a couple years, got a little bigger, got stronger. Yea, it's great if you want to grab some attention and feel better about yourself, I guess. Whenever I'd run I'd hate the feeling of being skinnier/small and just flat out weak for the most part. Then I realized, I was operating in extremes. I was either only running or only lifting (with some eliptical after sometimes). Therefore, I started to do both in moderation and have been fine, just like some other posters mentioned.
I equate this moderation to almost anything in life. Think about it, a drink or two a day is great for you, more than that is bad, less than that is not as beneficial. Tons of saturated fat is bad, as is no saturated fat. I think you can apply this to just about anything, I'm sure we've all heard of the triangle dealing with the various aspects of life and how if we compromise one for another, it leads to an unhealthy life.
Also, in terms of Yates being an HIT proponent, you should read up on his history if you think that's what worked for him. If he does indeed recommend this today, I would say read up on Mike Mentzger, who did a similar trend, and almost went off the deep end in terms of training theories.
