I didn't tag it at all - I don't wish to participate with tags that don't go two ways. The way tags currently exist, for the original poster to tag something he or she must consciously think to himself "who am i going to piss off by posting this? And how can I go out of my way to not offend them?" Note that it should properly be tagged #digg, not #reddit... but it could just as easily be tagged #comics or #history or #beentheredonethat. I only get one and the only reason I have to apply it is to deliberately shelter my followers from it. The system, in that regard, is broken.

Note however that someone - you? - tagged it #reddit after I tagged it. As such if you'd been patient you wouldn't have had to look at it at all. The system, in that regard, is functional.

Also note that now that it's been tagged #reddit, I can never un-tag it. Had someone tagged it #rddit or #reddt by mistake, we'd be stuck with it and someone else would have to notice.

I think a lot of functionality was destroyed when tags went away - for example, the structure of Hubski now requires power users, who were essentially the downfall of Digg. As I'm just one step below Kevin Rose in this analogy, I hope I have some credibility when I say that in my opinion, the ability to ignore tags without the ability to follow tags is a big step backward in fluidity and diversity.
