No, of course not. What would be the economic incentive towards carrying out a sufficiently complex MITM attack on a blog or a newsfeed?
In my experience the times that I've had users complain about "injected" information or weird ads, it's usually come from malware that resides ON their system. There's no MITM required for this. The injection happens client side through a browser plugin or some other resource that gets loaded up along with the page. TLS wouldn't fix this in any way as far as I am aware.
