Adding a button to temporarily follow a question

I quite often spot a question I'm interested with an answer, I'd like to tag it, or bookmark it, or mark it "inform me when changes with this appear". For now, I can add some comment like "cc me please if any answer show up on this" to get myself subscribed for question, however such comment is obviously non-constructive garbage :)
