Saw an interesting write up (please read) on learning and talking during Kriyas Hatorah.
I pretty sure I know who the author of this is and he's a great guy, a wonderful learner and all, but I think he may be a bit off on this pashat. At the end he is saying you would be permitted to talk bein gavrah l'gavrah which I don't think is how we posken.
Futhermore - the case brought down involves someone learning on the level of Rav Sheshas - that was something that was hard to reach even in the time of Rav Sheshas - all the more so today. I don't care how much Torah someone learns they can't be considered to be as high as Rav Sheshas - that they don't need to listen to leining.
Just my take.
