Yes, you are right, but from my discussions with others, it does not seem like very many people are really browsing the tags seriously enough yet. We should use them and we will (have to) use them as more content gets posted, but I am a little wary of relying on them at this point for people to find informational postings. We certainly do need stickied content; it would put me halfway out of a job (as a writer who has done far more 'how to' stuff than I ever wanted), but I'd support some stickies in a heartbeat.
