|All happen at the same time in 2019|
I get that as more and more comic-cons happen it makes it harder not to have overlap. I often see think-pieces asking if, "We have too many comic-cons?" or such, but disagree with any argument there are too many cons. There is such a wide range of interests, fandoms, etc. that I feel plenty of cons in existence is a good thing to have. The problem is when cons of similar focus, not too far from each other geographically, comparable in popularity, or a mixture of those factors find themselves happening at the same time. It just makes things harder for everyone and as I said, is dangerous for the continued success of the cons as it makes people choose sides/favorites.
