I think my biggest failing on this sort of thing is when I come onto a long thread, I have a tendency to scan the posts trying to get the gist of what people have said and there have been occasions where I have missed a point for that reason.I should be more careful but I'm afraid that is just me although I do apologise when I realise I have made such an error.
When it comes to reading threads (and I'm a fine one to talk with my spelling mistakes, typos and bad grammer) one thing I have trouble with is a very large block of text that has not been split up into reasonable sized paragrahs. I don't know whether it is my eyesight, my mind or what but I find them very difficult to read and regardless of how good the content may be, I skip them comlpletely rather than struggling to read them and I will continue to do so.
