I would like to think it does make you a better photographer. But it's a two-sided coin ... on one hand ... if you take what you've learned shooting a certain genre and apply it to a new/different genre, to your advantage. Then shooting a bunch of different stuff does help make you a better photographer. That is when experience enhances your skill. On the flip side, shooting a bunch of different stuff does dilute your expertise in one particular genre.
Hey John, this is your thread, what do you think?

Well, with regard to your "dilution" comment I don't know as it's quite true as you stated it though there's truth there. I'll modify that slightly and say "chops" in the sense of a musician rather than "expertise". If you play country music all the time, when you go to a jazz jam you might find yourself stumbling until your mind re-wraps itself around jazz -- even if you used to play a lot of jazz. There are some guys who just are always on point with anything -- but for us mere mortals we tend to be most fluid at what we drill on all the time.
So, when you tend to shoot certain genre's you do get somewhat biased in that creative "language" so-to-speak. However, if you had expertise in something else it's just a matter of drill and recall usually to get back to it. At least that's how I perceive it in my own life, lol. I'm picking at nits on your language though probably, sorry.
But on the original topic I think I'm seeing that really those two choices are, as you said, two sides of a coin. There is an interplay between gear capability and your inclination to shoot that can't be ignored. I pride myself -- and pride goeth before a fall, lol -- on being a photographer whose vision and "chops" can to some extent overcome the limitations of the gear I'm using. I work to ensure I have mastered my gear (to my own satisfaction at least) for what I do.
I think I started this topic to a great extent to express an impatience I have with gear discussions sometimes. Yes, I have opinions also but it seems they sometimes go on ad-nauseum and seem to miss the point of what's involved in actually making images. I wanted to see how people think and I'm actually quite impressed with what I've read here.
We had folks who came down more on one side or the other -- but when you read between the lines of their replies you see nobody either said "gear just doesn't matter" or "gear defines your imaging result entirely".
So, from that standpoint, I think only a fool would pedantically defend only one position over the other -- and we don't seem to have any fools here!
Thanks for an enjoyable discussion and if anyone else wants to chime in then keep the comments coming. Your comments have helped me clarify my own thinking on these issues.
