@DrewDad,
Here's some more on tagging.

Essentially, like a lot of other things with the site, it needs some time and usage to develop. 200 tags are nice, but 20,000 are a lot more meaningful. Then topics really start to pop for people.
And yes, you can see my tags, and I can see yours.
Tagging is best explained here:

A means of bookmarking could be something that's been available all along, which is to simply make the discussion url a favorite in Internet Explorer or Foxfyre or whatever browswer you're using.
Of course you're free to use the site as you think best, which is our philosophy driving this change in the software.
I'm sure you'll find new and interesting ways to use the software, and I hope you'll post your finds here or elsewhere. Thanks for asking.
