Even a long reply without any quote can sometimes be boring to read not to talk post with many quotes.
Maybe 2-6 quotes on a single reply is ok?
I agree with you, post that are too long and include many quotes are very hard to read. And the real subject of the thread gets lost sometimes. In my opinion 2 quotes are totally fine, but if you have 6 of them it's too much already. I use the forum a lot on my tablet or my smart phone, so the longer the post the more I need to scroll. One compromise could be to make an App for the phone that could let you collapse all quotes as default when being on the phone.
