Totally support this, I access Bitcointalk mostly with a mobile phone and I can testify that there are times when I want to scroll and I mistakenly touch a link and it opens right away without any kind or form of warning, and when this happens, I have to press the back button to return back to the page I was before.
There are times too when If I want to zoom the content of the page to enable me see the words clearly, the above happens too.

Introducing a pop up warning notification before opening a link will be really helpful, I believe this won't be to difficult to implement since we already since we already have a similar pop up whenever we click the "watch" topic or "unwatch" topic button, similar pop up can be built to come up when links are clicked too.
