2. If I want to give reply on any specific post then I just quote the specific part. I don not quote full reply as well.
I just quoted this part of your post to serve as an example, imagine if I had quoted your entire post, just to emphasize the point above, it would be difficult to understand and no user would enjoy reading it.
People who abuse quotes must take note that if the want to reply to an OP(thread), but do not have a particular or specific point in the OP that they wish to communicate on, then they should just go ahead and write it out without quoting, and if its a reply to OP that they want to quote, but do not have any specific part they want to underscore, then they can clear out the whole post and represent it with anything like: snip, < >, etc.
