That's a terrible false equivalency, but I will bit because indeed stadiums / arenas are not created solely as a sports venue. They would not be profitable if they were. Hmm...did someone say profit on a board that grades comic books?
1. I posted 5 threads that were simply from the first two pages of the Modern's section. Not the entire board, not the entire section, two pages. There are many that come on here to simply look at those type of threads.
2. Take a look at the latest posts which are cross-posted in the Pre-Heat Speculation Thread - Get it before it gets HOT thread.
3. Pretty much any "spec site", as they are lumped under one blanket, report current market trends, not solely speculation. That is part of the appeal and what many new to the market of selling now think is speculation.
In general "spec sites" as they are referred to are very similar in nature to the status of all comic book social media sites. They post news on current stories and trending topics in the comic book realm. Since the demise of Google +, the more popular and heavily moderated "spec sites" have moved to other social media platforms such as Facebook, MeWe, Reedit and chat forums (CGC). These larger user platforms have become troublesome to moderate for people that are not getting paid to do so. If you visit these sites now you will see that they are littered with information that is not relevant to speculation. Maybe 25% is actual speculation, 25% is market reporting and 50% are general questions from new comic buyers / sellers (How do I get a book graded? What's the grade of this? Should I sell or hold this? Here are my Wednesday pickups...etc.., much of the like can be found on CGC)
