The replies don’t follow a timeline so it’s hard to see how the exchange of information is made between people. You read someone asking a question who posted on Sept 2017 and then the next reply is from someone from March 2017. Then someone else provides a solution to the problem from Sept 2017. When you read it thinking that it follows a timeline, the provided solution does not make sense because you think the solution is for the problem from March 2017. Now imagine when the thread is especially long with interesting information. It’s a nightmare.
You spend more time doing matching between comments than actually read upon the solutions that might help you solve your problem.
