This can be done today, and is entirely unrelated to a voting system (use the favorites/bookmarks option of your browser).
...or by subscribing to the thread, which will then show up in "MyFlyertalk" (for really high-priority stuff, you can even have it email you.)
On a shared level, there are also sticky threads, and stuff that goes out in TalkMail or on the front page.
