Why is this so useful when it only requires just 1 single extra click now? Instead of clicking the name in the quote, we can now click the up-arrow in the quote, we are transported to the post that is quoted and there we just have to click on the Avatar to access the Membercard.
When you think about in practice I never have the need to click on the name in the quote-border, so for me (I understand it's different for everybody) there is no added value for it to be a link. However, what is indeed of value is the fact that we can press the up-arrow, because often I am interested in the post that has been quoted, especially when only a small portion of the source postings is quoted. And as I said... there we have the opportunity anyway to click on the Avatar to access the Membercard.
